The optimum conditions for the removal of leather tanning agent syntan from aqueous solution byFenton oxidation at 22 8C for an initial syntan concentration of 500 mg/L were pH 3, and concentrationsof H2O2 and FeSO4 of 300 mg/L and 500 mg/L, respectively. Fenton oxidation followed by granularactivated carbon (GAC) adsorption in fixed-bed column resulted in more than 95% removal of dissolvedorganic carbon, compared to 55–70% removal by Fenton oxidation alone and GAC adsorption alone. Theremoval of individual organic fractions was also higher for the combined treatment compared to theFenton oxidation alone.

Tin selenide alloy was synthesized by following simple chemical reaction method, at comparatively lower temperature of 100 ℃, from alkaline medium using SnCl2.2H2O and selenium as source materials. Powder X-ray diffraction analysis reveals that the particle size of the synthesized product is in nanometer scale. Using the reaction product as source material, the SnSe films were deposited on glass substrates at room temperature, 150 ℃, 250 ℃, 350 ℃ and 450 ℃. Structural, elemental, optical, surface morphological and electrical properties of the as deposited films were studied by X-ray diffraction, Energy Dispersive X-ray Analysis, UV-Vis-NIR, Scanning Electron Microscopy and Hall effect measurement techniques and the relevant details have been obtained.
