摘要
以吡咯烷二硫代氨基甲酸铵（APDC）法萃取分离饲料级硫酸锰中的铅,利用电感耦合等离子发射光谱仪进行测定,克服高锰基体的干扰,测定铅的回收率为98.73％～104.64％,方法检出限为0.007 42 mg/L,本法灵敏度高,检出限低,回收率较好.
Using Pentazane n-II for amino carboxylic acid ammonium （APDC） in separation of feed level sulfuric acid MN off lead, we find out the inductance in coupled plasma launches with spectrometer for determination. It overcomes high Mn substrate of interference, with determination lead of recovery for 98.73% - 104.64%. This method detection in limit is 0. 007 42 mg/L with high sensitivity and low detection limits, and the recovery is good.
