采用吡咯啶二硫代氨基甲酸胺(APDC)—氯仿体系作提取剂,氢化物发生—原子吸光光谱法测定,对成分复杂的海水中的不同形态砷进行了分离测定。
Pyridine dithiocarbamate (APDC) -chloroform system was used as extractant, and hydride generation-atomic absorption spectrometry was used to separate and determine the different forms of arsenic in seawater with complex composition.
