塞曼石墨炉原子吸收光谱法直接测定垃圾焚烧废气中锡
GF-AAS DETERMINATION OF TRACES OF TIN IN WASTE GAS FROM REFUSE INCINERATION WITH ZEEMAN EFFECT-BACKGROUND CORRECTION
摘 要
采用钯加抗坏血酸溶液作为基体改进剂,用塞曼效应扣除背景,对消化后的垃圾焚烧废气滤筒直接进行测定.方法的检出限为100 pg,线性范围为0.2-4 ng,回收率为96.8%-102.0%.

Abstract
A GF-AAS method was established for the determination of trace amounts of tin in waste gas from refuse incineration.Palladium nitrate and ascorbic acid were selected as matrix modifier.Zeeman effect was used for the correction of background absorption.Detection limit of the method was 100 pg (3σ).Linearity was in the range of 10-200 μg·L-1.Results obtained by test for recovery were in the range 96.8%-102.0%.
