T(4-TAP)P分光光度法测定瓷餐具铜溶出量

The Determination of Copper Solved From Porcelain With Porphyrin T(4-TAP)P Spectrophotometry

提出用四 - ( 4 -三甲铵苯基 )卟啉 [T( 4 - TAP) P]分光光度法测定陶瓷餐具中铜的溶出量。该方法灵敏度高 ,选择性好 ,操作简便快速 ,结果令人满意。

The spectrophotometric method with porphyrin T(4 TAP)P as a colour reagent to determining trace copper solved from porcelain was investigated. The porphyrin was found to have high sensitivity and high selectivity. The method was simple and the results were satisfactory.
