摘要
本文主要通过实验研究测定地质样品中的锡含量，以及锡与溴化十六烷基三甲胺—水杨基荧光酮的显色反应，其中光度法试验表明，在0.5~2.5mol.L-1的硫酸介质中，在溴化十六烷基三甲胺(CTMAB)存在下，锡与水杨基荧光酮(SAF)可形成稳定的红色配合物，在分光光度计上，以试剂空白溶液作参比，于510nm波长处测定吸光度；另外也通过实验证明了氢化物发生法在测定锡元素中的作用.
Abstract
This paper Determination of tin content in geological samples, and the color reaction of tin with cetyl trimethylamine- salicyl fluorone the experimental study, including photometric tests showed that, in the 0.5 ~ 2.5mol.L-1 sulfuric acid medium, the presence of the cetyl trimethylamine (CTMAB), tin salicylfluorone of one (SAF) to form a stable red complex spectrophotometer and a reagent blank solutionas reference, the absorbance was measured at 510nm wavelength;hydride role in the determination of tin element is also proved by experiments.
