摘要: |
分别用原子荧光法(AFS)和电感耦合等离子体质谱法(ICP-MS)测定水中锑。AFS法和ICP-MS法均线性良好,相关系数分别为0.9998和0.9999,检出限分别为0.17和0.03μg/L,〖JP3〗相对标准偏差均<1.15%,加标回收率分别为96.6%~111.9%和95.4%~111.5%,2种方法均能很好地用于水中锑的测定。其中,ICP-MS法适合较清洁地表水和地下水样品中锑的分析,AFS法则对地表水、地下水和废水样品均适用。 |

Abstract: |
Antimony in water was determined by AFS and ICP MS methods. The linearity was good for antimony determined both by AFS and ICP MS,with correlation coefficients 0.999 8 and 0.999 9,respectively. The limits of detection were 0.17 and 0.03μg/L, respectively. The RSDs of both methods were less than 1.15%, The recoveries were in the range of 96.6 %~111.9%, and 95.4%~111.5% for AFS and ICP MS, respectively.Both of the two methods can be used to determine antimony in water samples effectively. ICP-MS was better for the determination of antimony in cleaner surface water and groundwater, while AFS was more suitable for surface water, groundwater and waste water. |
