چکیده
a comparison of the photoefficiency of ni(ii) and nis incorporated into zeolite p towards photodecolorization of eriochrome black t dye solution was investigated in a photocatalytic reactor using uv lamp as a light source. the effect of various experimental variables on the decolorization performance of the process was evaluated by examining catalyst dosage, temperature, initial dye concentration and ph of the dye solution. the obtained results showed better efficiency of nis/p than ni/p catalyst. the decolorization process in both case obeyed first-order kinetics.

متن کاملSynthesis of novel perfluoroalkylglucosides on zeolite and non-zeolite catalysts.
Perfluoroalkylglucosides comprise a very important class of fluorine-containing surfactants. These compounds can be synthesized by using the Fisher reaction, starting directly from glucose and the required perfluoroalcohols. We wish to report on the use of zeolite catalysts of different structure and composition for the synthesis of perfluoroalkylglucosides when using glucose and 1-octafluorope...
متن کاملAzo-dye Orange II degradation by Fenton’s reaction using Fe/ZSM-5 zeolite as catalyst
This work deals with the non-biodegradable azo-dye Orange II degradation using the heterogeneous Fenton-like reaction using Fe/ZSM-5 zeolite as catalyst. The influence of some relevant parameters was studied, namely pH and temperature in the ranges 3.0 – 8.5 and 30 – 53 oC, respectively. Decolorization degree, TOC removal and leaching were evaluated along time in the experiments done. It was fo...
