摘要
以离子交换法去除干扰离子,二苯碳酰二肼为显色剂,采用流动注射技术,以60个样/h的速度,分析电镀废水及其他废水中的C_r^(6+)。线性范围为0～5.0mg/l,检出限为0.09mg/l;对1.0mg/lC_r^(6+)标准溶液连续测定12次,其相对标准偏差为1.1％。
A new method for determining trace Cr^(6+) in industrial wastewater by using flow injection-Photomet- ric analysis was presented. It was easy to operate, quick for analysis, accurately and precisely. The method also could be used in analyzing trace Cr^(6+) in other aquatic solution samples.
