摘要
研究了锑 ( )和锑 ( )在 DDTC-MIBK体系中的萃取和反萃取行为 ,用缝式石墨管原子捕集技术结合火焰原子吸收法测定了水样中的痕量锑 ( )和锑 ( ) ,线性范围为 2 .0～ 60μg/ L,检出限为 0 .4μg/ L,特征浓度为 1 .5μg/ L / 1 %吸收 ,相对标准偏差为 2 .6% ,锑回收率为 93 .0 %～ 1 0 5.0 %。
The extraction and back extraction behaviors of Sb(Ⅲ) and Sb(Ⅴ) in water samples with diethyldithiocarbamate and methyl iso butyl ketone have been studied. The trace Sb(Ⅲ) and Sb(Ⅴ) were determined with a linear range of 2.0～60 μg/L, a detection limit of 0.4 μg/L, a characteristic concentration of 1.5 μg/L/1% absorption and a relative standard deviation of 2.6% by using the title method. The recovery and enrichment factor of antimony are 93.0%～105.0% and 100, respectively.
