摘要
用ICP──AES法获得Ag、Al、Ba、Cr、Fe、Mg、Ni、Ph筹8个元素对As189.042×2nm分析线的干扰图,并测定了干扰程度。实验结果表明;浓度为As含量100倍的Ag、Ba、Fe、Mg、Ni、Ph对As分拆线几乎没有影响,而浓度为As含量100倍的Al和Cr对As分析线有一定的干扰.提出了校正和消除Al、Cr干扰的一些方法。
The interference pattern of eight elements such asAg, Al, Ba, Cr, Fe, Mg, Ni and Pb to As 189. 042×2nm analysis line is obtained by ICP - AES method aswell as the interferance level is determined. The experi-ment indicate. that As analysis line is rarely impactedwhen the concentrtiona of Ag, Ba, Fe, Mg, Ni and Pbare 100 times as much as As concentration, but As analy-sis line is impacted to some extent when the concentra-tions of Al and Cr are 100 times as much as As conentra-tion. Some methods for correcting and eliminating the in-terference of Al and Cr are presented.
