Abstract

Abstract

In this paper, micro-scale zinc-copper (mZn/Cu) bimetallic particles were prepared via replacement reaction and applied in the removal of Rhodamine B. The effects of initial pH, mZn/Cu dosage and initial concentration on the degradation of Rhodamine B were investigated. The optimal conditions for the degradation of of Rhodamine B was determined through single-factor experiment. As compared with single metals, the formation of microbatteries on mZn/Cu greatly improved its ability to provide electrons and its chemical activity, resulting in more efficient degradation of Rhodamine B. When N₂ was bubbled into the reaction system to remove the dissolved oxygen and the scavengers such as tert-butyl alcohol (TBA) and benzoquinone (BQ) were introduced, the degradation of Rhodamine B was also greatly inhibited. This proved that under acidic and aerobic conditions, the dissolved oxygen could accepted electrons from the surface of mZn/Cu to produce ·OH and O₂^-· radicals responsible for the rapid removal of Rhodamine B. Thus, this study not only provided a low-cost and high-efficiency technology for the degradation of organic contaminants in aqueous solution, but also put insight into the mechanism of the reaction.
