α,β,γ,δ-四-(4-吡啶)卟啉分光光度法测定瓷餐具铜溶出量

Determination of Copper Dissolved from Tablewares with α,β, γ,δ - Tetra - (4 - Pyridy )Porphyrin

本文提出用α,β,γ,δ-四-(4-吡啶)卟啉为显色剂,分光光度法测定瓷餐具铜的溶出量,该方法灵敏度高,选择性好,可以不经分离,直接对试样进行测定,操作简便,结果满意。

In this paper, the spectrophotometric method with α,β,γ,δ - tetra - (4 - Pyridy)porphvrin was investigated. The potphyrin was found to have high sensitivity and good selectivity.The method can be directly applied to determination of copper solved from tablewares .The results were satisfactory.
