摘要
基于流动注射预富集技术,结合MPT原子发射光谱仪建立了富集FIA-MPT-AES法。用该方法对电厂锅炉蒸汽中的痕量铜进行测量研究。在优化的实验条件下,对测量铜的检出限为2μg/L;连续进行测定,相对标准偏差为2.26%。
The method of combination of flow injection preconcentration and MPT-AES had been studied. A kind of flow injection preconcentration system has been developed to couple with MPT-AES to determine Cu in power station boiler steam. It was found that this kind was system could improve the analytical performance of MPT-AES. The detection limits of this method for Cu is 2.0μg/L. Results obtained for Cu in standard reference materials showed that there was no significant difference between the certified and determined values. The method can be applied to the determination of Cu in steam of power station boiler.
