系统研究了有机溶剂对多元配合物In-铬天青S-烷基三甲基溴化铵显色反应的溶剂化效应.发现与水混溶的乙醇、异丙醇、丙酮等含氧有机溶剂可以使多元配合物的分析性能优异化,大幅度地提高多元配合物显色反应的灵敏度和选择性.用这类体系测定了纯铝及铅中的微量铟.测定了配合物组成、有机溶剂化数、真正(?)值及表观稳定常数K.探讨了有机溶剂化效应的机理.
The solvating effects of organic solvents on the color reaction of the multi-complex In-chrome azurol S-alkyltrimethylammonium bromide were systematically investigated. It was found that water-miscible organic solvents such as ethanol, isopropanol and acetone Which can improve the analytical performance of the multi-complex and greatly improve the sensitivity and selectivity of the color reaction of the multi-complex.The trace indium in pure aluminum and lead was determined by this kind of system.The composition of the complex, the organic solvent The real number (?) And the apparent stability constant K. The mechanism of organic solvation effect was discussed.
