摘要
介绍了利用解联立方程组的方法,在紫外可见分光光度计上实现了对酸性红、酸性棕和酸性黑的混合染料中三种成分浓度的同时测定。该法不需要预分离,可直接测定,操作简便。测定结果比原用的比色法测定结果更加可靠,本方法对于相关化工产品的分析测定具有一定的推广应用价值。
The article presents a simultaneous determination method for three kinds of water-soluble dyes: acid red, acid brown and acid black by solving simultaneous equations using a UV-VIS spectrophotometer. The proposedmethod is simple and easy to operate. It can be used to analyze the samples directly without preseperation. The determination results are more convincible than those of using colorimetry. This method is of value to further application in determining some chemical products.
