摘　　要：三氮烯类试剂光度法测定贵金属,国内始于20世纪80年代,但其进展极为迅速,目前已合成和应用了74种这类试剂与银、钯、铂、金、铱的显色反应研究,相继发表了76篇论文。由于这类试剂发展迅速,其名称极为混乱,为了给试剂正名,提出规范试剂名称的原则。并归纳了这类试剂与贵金属显色反应的各种体系,经筛选分析,找出了测定贵金属的高灵敏试剂和体系。The study on the triazene chromogenic reagents for the determination of precious metals by photometry began in the 1980s in China. Since then, it has been making a fast progress and about 76 related papers have repored. This paper gives a review for the research achievements on gold, silver, platinum, palladium, iridum determination with 74 triazene chromogenic reagents, including the reagents structure, classifications and its chaotic names. This paper suggested the reagents naming standards, concluded its chromogenic characteristics and analytical systems, and filtered off out the better reagents and chromogenic systems for the determination of precious metals. 78 references are cited.
