摘要
本文提出了一个测定铑的超高灵敏的新方法——吸附光度法。摩尔吸光系数e为2.5×10~6,它是目前测定铑灵敏度最高的方法。铑量在4～100ng/ml范围内呈线性关系。所拟定的方法可用于某些低品位物料中铑的分析,对其超高灵敏的显色反应机理进行了探讨。
A new highly sensitive adsorption spectrophotometry oE rhodium has been developed.The molar absorptivity is 2.5X103 at 621nm.Beer's law is obeyed for 4-100ng Rh/ml.The method has been applied to determination of rhodium in some samples. The hypersensitive colour reaction theory of the system has been studied.
