Study on the Color Reaction of Halogen Substituted 8-Quinolyl Azo H Acid With Metal Ions Based on Quantum Chemical Calculation

本文研究了5,7-二溴-8-喹啉偶氮H酸和5-碘-8-喹啉偶氮H酸与Co^(2+)、Ni^(2+)、Cu^(2+)、Cd^(2+)、Pd^(2+)等离子的显色反应,并用量子化学理论探讨了取代基对显色剂及其分析性能的影响,着重研究了显色剂与Co^(2+)形成的配合物的键合情况,得到较为满意的结果.

The color reactions of 5.7-diBrQAH and 5-1QAH with Co2+、Ni2+、Cu2+、Cd2+、Pd2+ were investigated. Discussion of the analytical characteristic of color reagents was based on quantum chemical calculation. Bonding of the complex of color reagents with cobalt is studied especially. A satisfactory result was obtained.
