| Abstract: | In this study,a modified diatomite was synthesized by exchanging with the anionic surfactant sodium dodecyl sulfate(SDS),and the adsorption of modified diatomite on the methylene blue and malachite green dye wastewater was studied.The influences of pH value,temperature,time and dosage on the discoloring rate of methylene blue and malachite green dye wastewater were researched.The results showed that the discoloring ratio of methylene blue was enhanced after modification,and reached 71% under following condi... |
