| Abstract: | Objective]The adsorption properties of composite materials to dyes were studied.Method]Graphene oxide(GO) was prepared by modified Hummers method and PANI-GO composites was obtained by dynamic interface polymerization process.The adsorption properties of different contaminating dyes in wasrewater were studied.Result]The experimental results showed that the addition of GO can significantly improve the adsorption capacity and efficiency of complex to dye.The optimal adsorption conditions were the amount of adsorption regents 1.2 g/L, pH 4 and dsorption time 50 min,the removal rate of chrome black T in water reached 94.04%.Under the same conditions, the adsorption performance of composite material was increased by 15%.Among three different dyes, the adsorption effect on methyl orange was the best.Conclusion]The composite material can be used for the adsorption of dyes in wastewater. |
