火焰原子吸收法直接测定饲料级硫酸锌中铅、镉

Determination of pb, Cd in Feed Grade Zinc Sulphate by FAAS

本文用火焰原子吸收法直接测定饲料级硫酸锌中Pb、Cd。方法回收率95～100％。检出限Pb为0.17mg/L,Cd为0.006mg/L。相对标准偏差Pb为5.06％,Cd为1.28％。

Determination of pb、Cd in feed grade Zins sulphate by FAAS is described in this paper. The recovery is 95～100%. The detection limit is pb = 0.17μg/ml, Cd = 0. 006μg/ ml. The RSO is pb=5. 06%, Cd = 1. 28%.
