摘要
建立了复杂组分中测定硫酸根的高压离子色谱法。通过选择色谱条件使高出硫酸根量1000倍的硝酸根不干扰硫酸根峰。测定μg/ml级的硫酸根时的精密度为3%,探测下限为0.1μg/ml,测定一次需15min,结果与离子选择电极法在误差范围内一致。
The ion chromatography method is established for determination of sulphate in HLLW. By selecting optimum chromatography condition the nitrate whose concetration is a thounsand times of sulphate does not interfere with determination of sulphate. In determining μg/ml sulphate the precision is 3%. Low detectable limit is 0.1 μg/ml. It takes about 15 min for finishing the procedure. The results given by If are in agreement with data of ion selective electrode within range of error.
