锡烟灰中锡含量的测定

摘要

文章研究了锡烟灰中锡含量的测定方法,样品经过焙烧除去大部分砷和锑,锌粉-硼砂-硼酸熔样,再经酸化处理,于盐酸溶液中,用铝片还原,以碘酸钾滴定测定完成.%This paper studied a method for determination of Sn in Sn ashes.The samples were calcinated to remove a large part of As and Sb,then dissolved by using Zinc powder-borax -boric acid method,folowing acid treatment,the samples were reduced by aluminium in hydrochloric acid solution.finaly,determination was finished via iodate titration.
