摘　　要：将样品用过氧化钠-碳酸钠混合熔剂熔融后,用硫酸洗出定容,苯萃取锡的碘化物。在硫酸溶液中锡与苯基荧光酮生成红色沉淀,用动物胶使其分散在溶液中,以此测定锡量。After the samples were treated with sodium hydroxide and sodium carbonate mixed flux fusion, then washed out with sulfuric acid to volume, the benzene extraction of tin iodide. In sulfuric acid solution Sn and Phenylfluorone generate red precipitate with gelatin dispersed in the solution, as the determination of tin content.
