摘要
提出了薄层树脂相光度法测定锡的操作条件采用在０．１ ｍｏｌ·Ｌ－１ 的介质中，以水扬基萤光酮（ＳＡＦ）为显色剂，用阴离子交换树脂吸着测定锡灵敏度比溶液光度法提高８０ 倍，除Ａｓ（Ⅲ） 、Ｓｂ（ Ⅲ） 、Ｆｅ（ Ⅲ）外，其余共存离子基本无干扰实测了天然水中锡，加标回收率９３％ ～９９％
In this paper,operation condition of the thinlayer resin-phase spectrophotometry determination of trace tin has been developed determination of traces tin in hydrochloric acid medium with SAF for thiazolylazo reagent and anion exchange-resin to adsorptive. The sensitivity is 80 time as high as the solution spectrophotomtetric. Besides As?、Sb?、Fe?,the other ion don′t disturb busicaly.The method has been used to determine fin in water which give a recovery between of 93%～99%.
