采用Agilent特有的快速序列式原子吸收AA240FS实现一次进样,顺序测定生活饮用水及水源水中低浓度的Cu、Mn、Fe、Zn等元素,相关系数均大于0.999,方法检出限依次为0.001、0.002、0.010、0.002 mg.L-1;样品中加入几十个μg.L-1的各元素,大多数测定结果 RSD<1%,且回收率在99%—119%之间,完全满足饮用水及水源水中高、低浓度Cu、Mn、Fe、Zn元素的直接测定.
Using Agilent’s unique rapid sequence AA240FS atomic absorption spectrometry to achieve a single injection, the order of determination of low concentrations of Cu, Mn, Fe, Zn and other elements in drinking water and drinking water, the correlation coefficients were greater than 0.999, the detection limits were 0.001, 0.002,0.010,0.002 mg.L-1; the sample by adding dozens of μg.L-1 of each element, the majority of the determination of RSD <1%, and the recovery rate of 99% -119%, fully meet the drinking Direct Determination of Cu, Mn, Fe, Zn Elements in High and Low Concentrations of Water and Source Water.
