Preparation of Iron-carbon Micro-electrolytic Filler and Its Application for Degradation of Xanthate
-
Abstract
Micro-electrolysis is an effective, inexpensive, green industrial wastewater pretreatment technology. In this study, micro-electrolytic fillers were prepared by using iron, carbon, binder and pore-forming agent as raw materials, and the effects of degrading and removing isobutyl xanthate were investigated. The reaction time, filler amount, and the effect of initial pH of simulated wastewater were mainly studied on the micro-electrolysis degradation of isobutyl xanthate, the product after degradation of isobutyl xanthate were determined by GC-MS. The results show that the optimum preparation conditions of the filler are: m(Fe)/m(C)=1 GA6FA 1, binder content 20%, pore former content 3%, calcination temperature 900 ℃ and calcination time 2.5 h. The optimum conditions for micro-electrolysis degradation of isobutyl xanthate are: simulated wastewater initial pH = 7, reaction time is 90 min, and the amount of filler is 500 g/L. Under these conditions, the final degradation rates of isobutyl xanthate, COD, and TOC were 89.91%, 79.91%, and 35.87%, respectively. The final products of micro-electrolytic decomposition of isobutyl xanthate are CO2, H2O and SO42-. Micro-electrolysis can be used to purify and remove residual xanthate in beneficiation wastewater.
