摘　　要：文章研究了锡阳极泥中锡含量的测定方法,样品通过焙烧,过氧化钠分解后,以热水浸取,过滤,使锡与铜、砷等干扰元素分离。滤液经酸化处理,于盐酸溶液中,用铝片还原,以碘酸钾滴定法完成测定。In the paper,the method for the determination of tin content in the tin anode slime was studied.The material were calcined and decomposed by the sodium peroxide,then soaked by hot water and filtrated to separate tin from the interference elements,such as copper and arsenic,etc.The filtration was acidified by hydrochloric acid and deoxidized by aluminum,then titrated by potassium iodate to complete the whole determination.
