摘　　要：高砷锑烟灰的碱性氧压浸出液中,砷质量浓度在25 g/L以上,研究了采用硫酸-铁盐法去除砷。结果表明:铁盐用量为n(Fe)/n(As)=1.75,用硫酸调溶液pH=6,在60℃下反应1.5 h,砷脱除率在99.5%以上,除砷效果较好。Arsenic mass concentration is over 25 g/L in alkaline oxygen pressure leaching solution of high arsenic antimony cigarette ash.The removal of arsenic by sulphuric acid-ferrous salt process was studied.The results show that under the conditions of iron salt amount of n(Fe2+)/n(As)of 1.75,pH=6,reaction time of 1.5 h,reaction temperature of 60℃,the arsenic removal rate is more than 99.5%,and the effect is better.
