昆明贵金属研究所李振亚系统地研究了金(Ⅰ)-氯化亚锡-孔雀绿显色体系及其光度特性,提出了一个测定金的超高灵敏的新方法——离心光度法,该法不仅灵敏度高,而且有简便、经济,重现性好的特点。λ_(max)=621nm,表观摩尔吸光系数为1.05×10~5 L·mol~(-1)·cm~(-1),金含量0.5～4μg/25ml,遵
Li Zhenya, Kunming Institute of Precious Metals, systematically studied the photometric properties of the gold (Ⅰ) -tinum chloride-malachite green system and proposed a new ultra-sensitive spectrophotometric method for the determination of gold High sensitivity, but also simple, economical, reproducible characteristics. λ max = 621 nm, the apparent molar absorptivity is 1.05 × 10-5 L · mol -1 cm -1, the gold content is 0.5-4 μg / 25ml,
