摘要
采用 Ａ Ｐ Ｄ Ｃ－ Ｄ Ｄ Ｔ Ｃ－ Ｍ Ｉ Ｂ Ｋ 体系萃取富集水样中的铅和铬（ Ⅵ） ，并利用空气－乙炔火焰原子吸收法测定其含量。建立了优化的测定条件，并对可能存在的元素作了干扰实验。本法测定铅和铬（ Ⅵ） 的相对标准偏差分别为３１ ％ 和２２ ％ ，回收率为９７５ ％ 和１０１１ ％ 。
The content of lead and chromium(Ⅵ) in water samples is determined by air-acetylene FAAS after concentrated by APDC-DDTC-MIBK system extraction. The optimum determination conditions are optimized and the test for the interferential elements that probably exist is conducted. The relative standard deviation for lead and chromium(Ⅵ) are 3.1 percent and 2.2 percent respectively. and the respective recovery rates are 97.5 percent and 101.1 percent.
