X-ray diffraction, UV-visible reflectance and surface area BET were used to characterize binary synthesized Nano composites. The results in this work were related to two causes; the abilities of MWCNTs towards creating more active species with TiO2-UV100 when dispersion in all the surface, which causing reduce in bandgap, leading to a slight shift in the absorption. The second; the XRD has shown that two samples were did not change in crystallized the anatase phase. According to the results MWCNTs can be used to enhance the activates of UV100 for produce high quantiles of H2 as compare with pristine case without impregnated.

The noises produce from instrumental sources and the physical properties of tubular structure and that represent by inter and intra Van Der Waals forces. Most of the noises were removed by using computerized programs while it is referred to nature of tubular structure with one or many sheets of graphene. The most of this noises represent the nature of structure which reduces with increase graphene sheets, thus removing it delete the specific proprieties of CNTs. The graphite behave the same properties of tubular structure which variant with number of sheets.

The process of oxidations were analysis by XRD and optics microscopic images which shows clear change in particle size of graphite after every steps of oxidation. The method depend on treatments the graphite with H2O2 in two steps than complete the last steps by reacting with H2O2/NH4OH with equal quantities. The process did not reduces the several sheets for graphite but dispersion the aggregates of multi-sheets carbon when removed the Van Der Waals forces through the oxidation process.

The yellow precipitate was drying at 100oC before heat treated at 400°C to obtain crystalline TiO2. The sample were characterized using FT-IR and X-ray diffraction spectroscopy which identified that product was mixture between two form anatase and rutile. The photocatalytic activity of synthesized TiO2 was tested in the degradation of Eousin yellow which compare with two form of TiO2. Evaluated the results was shown that H2O2 was succeed to preparing TiO2 from TiOSO4 with higher activity then anatase and rutile forms.

Hydrogel is a type of sorption technique used as a sorbent. As of now, adsorption is viewed as a cost-effective method that may be used as an alternative to traditional contamination treatment methods. Several techniques were utilized to determine the surface characteristics before and after the adsorption method, like fourier transform infrared (FTIR) and field emission scanning electron microscopy (FESEM) techniques. The effect parameter of the adsorption method was studied, such as the effect of equilibrium time and weight. The data showed that the best removal percentage was (E%=96.546%) and adsorption capacity (188.0 mg/g) in the same order. Thermodynamic factor studies have shown that the reaction is spontaneous, exothermic, and convenient.
