A central composite design (CCD) method was used to optimize the preparation of OSAC using microwave assisted potassium hydroxide. RESULTS: The optimum conditions obtained were 565 W radiation power, 7 min radiation time, and 1.87 impregnation ratio. This resulted in 98.55% removal of Cu 2+ , 95.32% of Cd 2+ , 98.19% of Ni 2+ 98.83% of Pb 2+ , 99.32% of Fe 2+ , 98.36% of Zn 2+ , and 85.15% of OSAC yield. The surface characteristics of the AC prepared under optimized conditions were examined by pore structure analysis, scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FT-IR). The BET surface area, total pore volume and average pore diameter of the prepared AC were 1280.71 m 2 g −1 , 0.604 cm 3 g −1 and 4.63 nm, respectively. The equilibrium data of the adsorption was well fitted to the Langmuir equation and the highest value of adsorption capacity (Q) on the OSAC was found for Fe 2+ (62.50 mg g −1), followed by Pb 2+ (23.47 mg g −1), Cu 2+ (22.73 mg g −1), Zn 2+ (15.08 mg g −1), Ni 2+ (12.00 mg g −1), and Zn 2+ (11.72 mg g −1). CONCLUSIONS: OSAC prepared by microwaves can be used for the removal of metals from contaminated wastewater.

Textile fabrics were coated with silica nanoparticles prepared from tetraethoxysilane (TEOS) to obtain sufficient roughness with hydrophobic surface chemistry. Then the coated fabrics were treated with polydimethylsiloxane (PDMS) and aminopropyltriethoxysilane (APTES) to reduce the surface energy. The effects of PDMS concentration on the surface morphology and superhydrophobicity of as-prepared fabric were investigated. The morphology and the composition of superhydrophobic fabric was characterized by scanning electron microscopy (SEM), energy dispersive X-ray (EDS) and Fourier transform infrared (FTIR) spectroscopy. The results revealed the formation of spherical silica nanoparticles with average particle size of 250 nm throughout the fabric surface. The possible interactions between silica nanoparticles and APTES, as well as the fabrics were elucidated. Investigating the hydrophobicity of fabrics via water contact angle (WCA) measurement showed that the treated fabric exhibits excellent water repellency with a water contact angle as high as 151° and a very low water sliding angle. It also found that the treated fabric maintained most of its hydrophobicity against repeated washing. The comfort properties of the obtained superhydrophobic fabrics in term of air permeability and bending length did not reveal any significant changes.

The effects of process parameters, including oxygen gas concentration, treatment time, and density of the sample on the resulting hydrophilicity of the fabricated product were measured in terms of relative weight increase caused by the adsorption of water and water contact angle. The results indicated that the PP NWF modified by reactive magnetron sputtering at an oxygen gas concentration of 40%, a treatment time of 20 min, and a density less than 500 g/m 2 showed improved hydrophilicity. In addition, the surface morphology and chemical composition of the treated samples were examined by scanning electron microscopy and X-ray photoelectron spectrometry. It was determined that the silicon dioxide nanoparticles were evenly deposited on the surface of fibres.

The chitosan-treated sample (PP-Ch) was coated with TiO 2 nanoparticles by a pad-dry method. Silver nanoparticles were in situ synthesized on the chitosan-TiO 2-coated sample by a chemical reduction method. The morphology of each of the samples mentioned above was evaluated by FESEM. The efficiency of each sample in the removal of C.I. Acid Brown 248 from aqueous media was evaluated. The PP-Ch sample removed 90% of the dye at pH=3. Coating the PP-Ch sample with TiO 2 and silver nanoparticles improved the dye removal efficiency under UV irradiation.

In order to enhance its adsorption performance, poly(propyleneimine) dendrimer was used to functionalize the as-synthesized magnetic porous nanocomposite. The dendrimer-functionalized magnetic nanocomposite was characterized by field emission scanning electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy, nitrogen adsorption/desorption isotherms and vibration sample magnetometer. The obtained results revealed the successful synthesis and functionalization of magnetic nanocomposite. The adsorbents exhibited good magnetic properties with high saturation magnetization and high specific surface area. The adsorption isotherms and kinetics of anionic dyes were described by the Freundlich and pseudo-second-order models, respectively. It was found that the kinetics of adsorption of both investigated dyes by dendrimer-functionalized magnetic composite is considerably faster than the magnetic composite under the same condition. The adsorption capacity of the dendrimer-functionalized magnetic composite for investigated direct and acid dyes was 173.7 and 122.5 mg/g, respectively, which was higher than the existing magnetic adsorbents. This work provides new insights into the synthesis and application of hybrid magnetic adsorbents with synergistic properties of nanoporous metal organic frameworks and dendrimer with large number of functional groups for removal of organic dyes.

The knitted fabrics were then made from these yarns and subjected to oxygen plasma treatment for 5 min. The samples were dyed with a disperse dye and an acid dye and the color strength, color coordinates, and fastness properties of the dyed samples were compared. The effect of plasma treatment on the surface chemistry and morphology of the samples was evaluated using Fourier-transform infrared spectroscopy (FTIR) and atomic force microscopy (AFM) analyses, respectively. FTIR analysis confirmed the introduction of oxygen-containing groups on the surface of the plasma-treated samples. AFM images confirmed etching of the fibers, and the surface roughness of the fibers increased significantly after plasma treatment. The incorporation of nanoclay in the multifilament yarns improved the dyeability of the polypropylene/nanoclay composite fibers with disperse and acid dyes. The optimum amount of the nanoclay for obtaining the highest color strength was 2 wt% and 1 wt%, for dyeing with the disperse and acid dye, respectively. Plasma treatment enhanced the dyeability and fastness properties of the fibers. The highest K/S values obtained on plasma-treated PP/nanoclay samples were 1.27 and 10.88 for acid and disperse dyes, respectively. The fastness properties of the samples dyed with the acid dye were generally lower than those of dyed with the disperse dye. The highest washing, dry rubbing, and light fastness properties were obtained on plasma-treated and disperse-dyed PP/nanoclay (2 %) sample, which were 4–5, 3, and 5, respectively.

In this study, the microwave-assisted extraction of colorant from cochineal insects for dyeing of bio-mordanted silk has been carried out. Acidic, methanolic, and acidified methanol solubilized media were used to extract the natural colorant from cochineal under microwave irradiation for 1–6 min. Bio-mordants have been employed at optimized conditions to make the process greener and sustainable. It is found that acid solubilized extract of pH 4, employed at 55 °C for 55 min containing 5 g/100 mL of Glauber’s salt as exhausting agent has given high color strength onto microwave-treated silk fabric. Suggested ISO standards for colorfastness have revealed that bio-mordants have given excellent color depth and excellent rating of fastness properties, compared with chemical mordants used. It is found that microwave treatment has not only improved the dyeing behavior of colorant extracted from cochineal in acid solubilized medium but also enhanced the color characteristics onto bio-mordanted silk fabric.

In order to achieve this goal, Rhubarb flower parts were used to produce a brown hue on nylon 6 fabric. The effects of dyeing parameters such as dyeing time, temperature, dyebath pH, M:L, salt addition, dispersing agent, and dye concentration on color strength were investigated. Using 100%owf dye in an acidic medium at boil and the material to liquor ratio of 1:30 for 75 min was determined to be the optimal condition for dyeing nylon 6 with rhubarb flower. In order to achieve acceptable color fastness, four natural mordants were applied, including walnut husks, pistachio hulls, pine cones, and green coffee. Colorimetric measurements revealed that mordanting did not affect the hue of the color compared to the non-mordant sample. In addition, diverse natural mordants produced the same color (i.e., brown) with varying color strengths, of which 10%owf walnut husk generated the strongest color. Bio-mo...
