【摘要】 本文研究了在聚乙烯醇存在下钌（Ⅱ）-氯化亚锡-结晶紫离子缔合体系的高灵敏显色反应。离子缔合物的最大吸收峰位于550nm处,摩尔吸光系数为1.1×10⁶L.mol^-1cm^-1.钌含量在0.2—2.8μg/25mL范围内符合比尔定律。对外来离子的干扰和分离进行了研究。拟定的方法可用于矿石和一些低品位贵金属物料中钉的分析。更多还原

【Abstract】 A highly sensitive spectrophotometric method for the determination of Ru has been developed. The molar absorptivity is 1.1×10~6 L·mol~-1·cm~-1 at 550nm. Beer＇s law is obeyed for 0.2—2.8μg/25ml of Ru. Interference and separation of diverse ions are also investigated. The method is applicable to the determination of Ru in some precious metal samples.更多还原
