摘要
采用原子吸收分光光度法检测GSBZ50007-88、GBW(E)080112两个水标准样品的总硬度。实验结果表明,两个标准样品的检测结果均在标准值的范围之内,方法的相对标准偏差为1.7%,检出限为0.04mg/L。本方法解决了以往GB5750-1985法滴定终点难以判断的难题。
The total hardness of the standard water samples GSBZ50007 - 8 and GBW（ E）080112 were determined by atomi1 absorption speetrophotometry. The experiment results showed the total hardness of the samples were in the ranges of standard values. The RSD was 1.7% and the detection limit was 0.04 mg/L for this method. The problems of titration end - point which was hard t1 determined using national standard method（ GB 5750 - 1985 ） were solved.
