摘要
本文采用自己合成的水溶性卟啉T(4-TAP)P作试剂,在pH45,盐酸羟胺存在下,建立了一种测定人尿中痕量铜的分光光度法,操作简便,结果准确,令人满意。
A spectrophotometric method for the determination of trace copper in urine has been developed.Sensitive water soluble,α,β,γ,δ—Tetrakis-(4-trimethylaminophenyl)porphine,i e,T(4-TAP)P is used as a color reagent in the presence of H 2NOH·HCl at pH 4 5 The RSD obtained is 7 4%(n=5) The average recovery is 91%(n=4) Its accuracy is comparable with AAS The results are satisfactory
