FAAS法测定硫酸中的铁和锌

Determination of Iron and Zinc in Sulphuric Acid by FAAS

本文建立了火焰原子吸收光谱法测定硫酸中铁和锌的方法，确定了最佳仪器工作条件和样品处理方法。在选择好的实验条件下，测定铁的特征浓度为０．０１４μｇ／ｍＬ／１％吸收；测定锌的特征浓度为０．００２μｇ／ｍＬ／１％吸收。回收率分别为铁９８．８％—１０３．４％，锌９２．５％—９８．６％。

A method for determining iron and zinc in sulphuric acid is established in the paper .The working parameters of instrument are determined.A method of sample decomposition is established.Under experimental conditions,characteristic mass are 0.014μg/mL/1% A for iron,0.002μg/mL/1% A for zinc ,recovery ration are 98.8%—103.4% for iron,92.5%—98.6% for zinc.
