摘要：

A few new spectrophotometric methods for the determination of trace amounts of tin(IV) have been developed based on the reaction of tin(Ⅳ) with tungstate and basic dyes(BD), which consists of rhodamine B(RB),butylrhodamine B(BRB) and nile blue(NB),to form ion-associations complexes of the kind in the presence of polyvinyl alcohol(PVA).
