摘　　要：为测定田湾核电站所使用的核级氢氧化钾固体中的阴离子含量,将氢氧化钾固体配制成浓度约为2%的溶液,经过阴离子抑制器进行前处理,抑制器通过电解水和膜渗透将样品中和,然后将前处理后的样品上离子色谱进行分析,可实现常见阴离子高灵敏度分析与检测。该方法重现性和线性好,且检测下限控制较低,各种阴离子的检测下限可达1μg/L级。To determine the anion content in the nuclear grade potassium hydrogen solid used in Tianwan nuclear power plant,the potassium hydroxide solid is prepared into a solution of about 2%to neutralize the sample through electrolytic water and membrane,and then analyzes the high sensitivity analysis and detection of common anions,with good reproducibility and linearity,and low detection limit control.The lower limit of various anions can reach 1μg/L level.
