固体热解－塞曼原子吸收光谱法用于粉煤灰样品中汞的快速测定
Rapid determination of trace mercury in fly ash samples by pyrolysis zeeman atomic absorption spectrometry
摘要
Abstract
In this paper a rapid and simple method using pyrolysis High Frequency Modulated light polar-ization coupled with Zeeman Atomic Absorption Spectrometry (ZAAS-HFM)was employed for the analy-sis of total mercury in fly ash samples.The factors those influence the experiment results,such as the sample matrix,quantity of samples,gas flow,memory effect,were studied.Under optimum conditions, the reproducibility of the method was within the range of 3.2% ~3.8% for peak area and 5.2% ~6.9%for peak height.The detection limit (3σ)was 0.002 0 μg·g -1 and the recoveries were within the range of 94.2% ~98.5%.Three fly ash samples and three standard reference materials were analyzed.These results were consistent with those obtained by the Cold Vapor Atomic Absorption mercury analyzer (CVAAS),as shown by the result of t-test,no significant difference was found between these two meth-ods.The method was simple,efficient and suitable for high throughput determination of total mercury in fly ash samples.关键词
