原子吸收分光光度法测定硫铁矿中铅锌

Determination of Lead and Zinc in Pyrite by Atomic Absorption Spectrophotometry

用原子吸收分光光度法测定硫铁矿中铅、锌，获得了满意的效果。锌在０～１．０μｇ／ｍＬ，铅在５～５０μｇ／ｍＬ范围内呈线性，回收率在９７％～１０５％。

Lead and zinc in pyrite were determined byatomic absorption spectrophotometry. The absorbances of lead and zinc were linear with their corncentrations of 0～10μg/mL and 5～50μg /mL respectively and the recovery reached 97%～105%.
