中文摘要: 对高砷铅阳极泥进行碱性体系通入空气脱砷试验，详细考察了碱用量、空气流量、脱除温度和反应时间对脱砷率的影响。结果表明，在氢氧化钠用量为1.4倍理论量、空气流量100 L/h、液固比5∶1、温度80 ℃、阳极泥粒度0.15~0.178 mm、脱除时间2 h的最佳条件下，脱砷率达到95%以上。
Abstract:Selective arsenic removal from high arsenic bearing lead anode slime was conducted in alkaline system by feeding air. The effects of dosage of caustic soda, air flow, leaching temperature and time on arsenic removing rate were investigated. The results show that the arsenic removing rate is 95% above under the optimum conditions including dosage of caustic soda of 1.4 times of theoretical value, air flow of 100 L/h, ratio of liquid to solid of 5∶1, leaching temperature of 80 ℃, size of anode slime of 0.15~0.178 mm, and leaching duration of 2 h.
