摘要
合成了六种Cadion类试剂,并研究了在TritonX—100存在下试剂与镉的显色反应。讨论了试剂结构与分析性能的关系。
Six color reagent for spectrophotometric determination of cadmium benzenedia-zoamimoazobenzene onitrobenzenediazoaminoazobenzene mnitrobenzenediazoaminoa-zobenzene pnitrobenzenediazoaminoazobezene 2, 4 dmitrobenzenediazoaminoa-zobenzene and 3. 5 dinitrobenzenediazoaminoazobenzene have been synthesized and in the presence of Triton X -100 the color reactions between the reagents and cadmium have been studied The sensitivity and selectivity of the reagent with a nitro group in the para position of the -N=N=NH- group in the Cadions'molecule is better than in the ortho and meta position.
