摘要
研究了碲（Ⅳ）和碲（Ⅵ）在 DDTC-CCI．体系中的萃取和反萃取行为，并用缝管原子 捕集技术结合火焰原子吸收法测定了水样中的碲（Ⅳ）和碲（Ⅵ），特征浓度为1.2 μg／L／1％ 吸收，检出限0.2μg/L，相对标准偏差1．7％，富集倍数可达100倍。
The extraction and back-extraction behavior of Te(Ⅳ) and Te(Ⅵ) in water sam- ples with diethyldithiocarbamate and carbon tetrachloride has been studied. Te(Ⅳ) and Te (Ⅵ) were determined with the characteristic concentration of l. 2 μg/L/1% absorption, with a detection limit of 0.2 μg/L and a relative standard deviation of 1.7%. The enrichment factor of tellurium is 100.
