摘要
原子荧光光谱法测定环境水中砷、硒和汞,试验了标准系列的配制方法;硼氢化钾浓度、盐酸酸度对测定的影响;优化了仪器条件。砷、硒和汞检出限分别为0.51μg/L、0.53μg/L、0.065μg/L,相对标准偏差(n=11)分别为1.51%、2.36%、1.63%,加标回收率分别为90.0%-105.0%、92.0%-97%、90.0%-97.5%。
The amounts of arsenic,selenium and mercury in environmental water were determined by AFS. The standard series method for sample solution and the effect of hydrochloride and potassium borohydride were studied. The instrument conditions were optimized. The detection limit for As,Se and Hg are 0. 51μg/L,0. 53μg/L and 0. 065μg/L with the RSD of 1. 51%,2. 36% and 1. 63%. The recovery are 90. 0%-105. 0,92. 0%-97% and 90. 0%-97. 5%,respectively.
