摘要
本文对锌合金中铜的快速分析进行了研究,建立了以BCO(双环乙酮草酰二腙)为显色剂的、锌合金中铜的单流路流动注射一分光光度分析方法.该方法具有操作简便、快速(采样频率为90样次/小时)、精度高等优点.对实际样品分析的结果与常规分光光度法一致.测定的线性范围为0~10pppm
A single line FIA system for spec trophotome trie determination of copper in zinc alloy is described. The method is based on the chromogenic reaction between copper(Ⅱ)and oxalic acid bis-cyclohexylidene hydrazide. Copper (Ⅱ) can be determined in the concentration range of O-10 ppm with Sampling frequency 90h~(-1). The proposed method is very simple, quick and of high precision. The result coincides with that obtained by ordinary spectrophometry.
