【摘要】 绕丹宁衍生物是光度法测定贵金属的一类传统显色剂,这类试剂容易合成,近年来涌现出一批新型绕丹宁衍生物,除测定贵金属外,已拓展到一些贱金属的分析测定。分析手段已由传统的吸光光度法向荧光光度法和催化动力学荧光分析法转移,使测定的灵敏度和选择性大大提高。根据文献检索,将国内在这一领域的研究应用现状进行介绍。更多还原

【Abstract】 The rhodanine derivative is a kind of traditional colour reagent for the photometry determination of precious metals.But in recent years,many new kinds of reodanine derivatives are easy synthesized and used for the determination of base metals.The analytical methods begin to change from traditional absorptiometry to fluorophotometry and catalytic kinetic fluorophotometry.According to documents research status of base metals determination at home was introduced.更多还原
