摘要
将铸铝合金待测试样用硫酸溶解，过滤后回收残渣中的锡。在硫酸介质中，以动物胶为分散剂， Ｓｎ（Ⅳ）与水杨基荧光酮反应生成微溶于水的红色络合物，用分光光度法即可测定试样中的微量锡。
Dissolve the aluminum alloy sample in sulfur acid solution, and reclaim Sn in the residue after filtration. with the animal colloidal solution as dispersing agent in sulfur acid medium, Sn (Ⅳ)reacts with salicyl-group-fluorescence-ketone and generates a kind of rarely dissolvable red complex then we can determinate the quantity of Sn in sample by spectrometer method.
