连续流动分析法与直接显色分光光度法测定水中硫化物的对比分析

Comparative Analysis Between the Continuous-Flow Analyzer and the Spectrophotometer

采用连续流动分析法检测水中的硫化物,并与直接显色分光光度法进行对比分析,结果显示两种检测方法差异不明显。和分光光度法相比较,连续流动分析法在精密度、准确度、稳定性、实验效率及自动化程度等诸多方面均占据优势,在水中硫化物检测中有较高的推广价值。

The sulfide in the water determined by continuous-flow analyzer is compared with the direct spectrophotometric method.The results show that there’s no significant difference between the two methods.However,the continuous-flow analysis has more advantages on many aspects,such as precision,accuracy,stability,experimental efficiency and automation,which is of high popularization value in the field of sulfide in water detection.
