两种仪器型号的离子色谱仪对饮用水源地下水中溴化物的测定对比研究

Comparative study on determination of Bromide in groundwater of drinking water source by two instruments of Ion Chromatograph

本文运用瑞士万通883和戴安ICS-1000两种仪器型号的离子色谱仪分别对饮用水源地下水中的溴化物进行测定分析比对,通过对比两种仪器测定方法的线性关系相关系数r(r>0.999)、检出限、精密度、准确度、回收率及相对标准偏差(RSD),其均能达到质量控制要求,且瑞士万通883和戴安ICS-1000在测定饮用水源地下水中溴化物含量方面各具有一定的优势。

In this paper,the ion chromatograph of Swiss Metrohm 883 and Dionex ICS-1000 were used to determine and analyze bromide in the groundwater of drinking water sources respectively.By comparing the linear correlation coefficient r(r>0.999),detection limit,precision,accuracy,recovery and relative standard deviation(RSD)of the two instrument methods,we found that all the parametes can meet the quality control requirements.And Swiss Metrohm 883 and Dionex ICS-1000 each has its own advantages in determining bromide content in the groundwater of drinking water sources.
