分光光度法测定氧化锌中总铜含量

Determining Total Copper Content in Zinc Oxide With Spectral Distribution Luminosity Method

提出分光光度法测定氧化锌中总铜含量的分析方法。铜与铜试剂（ＤＤＴＣ）反应产物的三氯甲烷萃取液在４３５ｍｉｎ的波长产生灵敏吸收，据此可进行光度分析。铜含量在０～５μｇ／２５ｍｌ之间符合朗伯－比耳定律，检测限为０．０１μｇ／２５ｍｌ，本法用于氧化锌中总铜含量测定，得到满意的结果。

The paper gives an analysis method of spectral distribution luminosity to determine the total copper content within zinc oxide. The reactant of copper and DDTC, trichloromethane extraction liquid produces a sensitive absorption in 43.5 mm valvelength, by which the luminosity analysis can be made. This method is mainly used to determine the total copper content in zinc oxide and it can achieve a satisfied result.
