研究高铁试剂及其与铜形成的络合物的紫外吸收光谱特性、络合物的形成条件，并拟定一个测定铜的紫外光度法．络合物最大吸收波长为λ＝２６４ｎｍ，摩尔吸光系数ε＝７．４×１０４Ｌｍｏｌ－１ｃｍ－１．灵敏度比可见光区法高７倍．
To study the UV absorption spectra of the high-iron reagent and its complexes with copper, the formation conditions of the complex and to develop a UV-spectrophotometric method for the determination of copper. The maximum absorption wavelength of the complex was λ = 264nm, the molar absorptivity ε = 7.4 × 104Lmol-1cm-1. Sensitivity than visible light method 7 times higher.
