Barium(II)bis(oxalato)barium(II)dihydrate (BOD), Ba[Ba(C2O4)2]·2H2O and lead(II)bis(oxalato)lead(... more Barium(II)bis(oxalato)barium(II)dihydrate (BOD), Ba[Ba(C2O4)2]·2H2O and lead(II)bis(oxalato)lead(II)monohydrate (LOM), Pb[Pb(C2O4)2]·H2O have been synthesized and characterized by elemental analysis, conductance measurements, IR spectral, reflectance and X-ray powder diffraction studies. Thermal decomposition studies (TG, DTG and DTA) in air showed that at ca. 1000°C, a mixture of BaO2 and BaCO3 is generated from the compound, BOD, through the formation of BaO2 and BaC2O4 at around

The complexes were characterized by elemental analysis, IR and electronic spectral data, conductivity measurement and powder X-ray diffraction (XRD) studies. The chromium(III)tris(oxalato)chromate(III)tetrahydrate (COT), Cr[Cr(C2 O4)3]·4H2O, released water in a stepwise fashion. Removal of the last trace

The compounds were characterized by IR, UV, SEM and TGA techniques. Conductivities were determined from 30 to 1500C in solid state within a frequency range 42Hz to 500kHz. Conductivity of the complex formed in nano fine state is more stable and shows dramatic improvement compared to the bulky one.

The present study unfolded the synthesis of a regenerative framework adsorbent employing greener condition, that shows excellent performance with an ultrahigh adsorption capacity and 99 % removal efficiency for a range of water polluting contaminants, i. e., organic dyes of industrial importance. A pseudo‐second‐order kinetics model shows a favorable fit for the adsorption process. The maximum adsorption capacity calculated by the Langmuir isotherm was found to be highest among many reports in the minimum concentration range, which directly indicates its outstanding efficiency even at lower contaminant concentration. The framework has good reusability and remarkable adsorption performance after being used for several repeated cycles. Consequently, the adsorption beha...

These ZnO nanoparticles were extended for remediation of pollutants present in paper mill effluents, and separation efficiency was found to be above 90% for hydrocarbons, 92% for lignin, 99% for phenol, and 93% of chemical oxygen demand (COD), as confirmed by gas chromatography-mass spectrometry and COD analysis. It was also observed that the experimental setup could successfully remove 99% of the color from the sample. These ZnO nanoparticles have been proven in the past to be antibacterial and were explored for its ability to inhibit the growth of both Gram-positive and Gram-negative bacteria in the effluent samples after the removal of toxic pollutants. Therefore, we proposed an electrochemical reaction for the in situ synthesis of ZnO nanoparticles for remediation of paper mill effluent as well as inhibit the bacterial growth in the treated effluent sample.
