α,β,γ,δ-四-(2-氯苯基)卟啉与镉反应的研究

The Reaction of Cadmium with α,β,γ,δ-Tetra-(2-Chlorophenyl)Porphrin as Studied by Spectrophotometry

应用新型卟啉试剂α,β,γ,δ-四-(2-氯苯基)卟啉与镉的显色反应,直接分光光度法测定痕量镉具有灵敏度高ε=4.4×10~5、操作简单、选择性及稳定性好的特点,应用于测定糖厂和造纸厂废液中的微量镉,结果满意。

Trace cadium is determined spectrophotometrically by applying the color reaction of cad- mium with α,β,γ,δ-Tetra-(2-Chlorophenyl)porphrin,a new type reagent.It is a method of high sen- ()ve(e=4.4×10~5),selective,and stable as well as simple In operation.It has been successfully ap- plied to the dertermination of trace cadmium in waste water from surgar mill and paper mill.
