Investigation of Immobilized Silver Nanoparticles –Catalyzed in Eliminating Trace amount of Acid Red 87 Dye with Peroxydisulfate from Contaminated Water

The present study was carried out to investigate the effect of silver nanoparticles to catalyzed peroxydisulfate in order to removal of acid red 87 from contaminated water, the simultaneous use of peroxydisulfate and nanosilver significantly increased the removal efficiency. the effects of various parameters such as peroxydisulfate concentration, contaminant concentrations and dosage of silver nanoparticles on the dye removal were evaluated. results showed that increasing the concentration of peroxydisulfate and nano-silver catalyst can increase the rate of pollutants removal. the optimal amount of nanosilver and the optimum concentration of peroxydisulfate were estimated 0.125g.l-1 and 10 mm, respectively.
