为了更好地处理水环境中的偶氮染料(酸性橙,AO7)污染问题,以稻壳、尿素和锰盐为原料,通过热解法制备Mn、N共掺杂生物炭复合材料(Mn-N-BC),活化过二硫酸盐(PDS)降解酸性橙(AO7)染料废水。考察了AO7初始浓...展开更多 为了更好地处理水环境中的偶氮染料(酸性橙,AO7)污染问题,以稻壳、尿素和锰盐为原料,通过热解法制备Mn、N共掺杂生物炭复合材料(Mn-N-BC),活化过二硫酸盐(PDS)降解酸性橙(AO7)染料废水。考察了AO7初始浓度、PDS浓度、催化剂投加量、初始pH值等因素对AO7去除率的影响。结果显示:Mn-N-BC/PDS体系对AO7染料具有较高的去除率,在30 min内可达为98.6%,其表观速率常数kobs为0.125 min-1;并...

In order to better deal with the problem of azo dye (acid orange, AO7) dye pollution in water environment, Mn and N co-doped biochar composites (Mn-N-BC) were prepared by pyrolysis method using rice husk, urea and manganese salt as raw materials, and acid orange (AO7) dye wastewater was degraded by activated peroxydisulfate (PDS). The effects of initial AO7 concentration, PDS concentration, catalyst dosage and initial pH value on the removal rate of AO7 were investigated. The results show that the Mn-N-BC/PDS system has a high removal rate of A...
