A new and highly sensitive reagent is proposed for spectrophotometric determination of cadmium. alpha,beta,gamma,delta-Tetrakis (4-N-trimethylaminophenyl) porphine forms a chelate with cadmium in alkaline solution with a molar absorptivity of 5.77 x 10(5)l. mole(-1).cm(t1), the largest value reported to date for a cadmium complex. An extraction method is described for selective separation of cadmium.
提出了一种用于分光光度法测定镉的新型高灵敏度试剂。α，β，γ，δ-四（4-N-三甲基氨基苯基）卟啉在碱性溶液中与镉形成螯合物，摩尔吸光系数为5.77×10⁵ l·mol⁻¹·cm⁻¹，这是迄今为止报道的镉配合物的最大值。描述了一种用于选择性分离镉的萃取方法。
