连续流动分析法测定降水中铵盐的可行性研究

A Study on the Determination of Ammonium in Precipitation by Continuous Flow Analysis

铵盐是降水监测的重要指标之一，它对降水中的酸性物质具有中和作用。将连续流动分析法应用于降水中铵盐的检测，并对该方法的检出限、精密度．加标回收率等一系列实验室质量要求进行了测定；在此基础上，用连续流动分析法和国家标准分析方法进行比对试验。对测试结果进行数理统计分析后证明，连续流动分析法与国标方法无显著性差异。

Continuous flow analysis （CFA） method was applied to the detection of ammonium in precipitation, and a series of laboratory quality requirements such as detection limit, precision, recovery and etc. were determined as well as compared with the national standard specified method. It indicated that there were no significant statistical differences between the continuous flow analysis and the national standard method.
