中文摘要: 采用一定比例的混合酸溶解样品,利用基体匹配配制一系列标液消除基体的影响,以及轴向观测喷嘴吹扫技术来提高待测元素的灵敏度,使用电感耦合等离子体发射光谱(ICP-OES)测定镍基/钴基高温合金中硼磷硅。各元素选的分析线依次为B 182.577 nm、P 178.222 nm、Si 185.005 nm。检测范围分别是:B:0.001%-3.0%,P:0.003%-0.20%,Si:0.005%-3.0%,检出限范围是0.00005%-0.0004%,线性相关系数>0.9995。加标回收率为90.0%-105.0%,精密度RSD<2.0%。该方法操作简单快速,结果令人满意。
Abstract:The sample was dissolved with some proportion of mixed acid. The standard solutions were prepared by matrix matching method to eliminate the influence of matrix effect. Adopting axial observation nozzle purging technology to improve the sensitivity of elements in nickel-based or cobalt-based superalloys by inductively coupled plasma emission spectrometry (ICP-OES). B 182.577 nm, P 178.222 nm and Si 185.005 nm were selected as analytical lines. The detection ranges were B:0.001%-3.0%,P:0.003%-0.20%,Si:0.005%-3.0%, the linear correlation coefficients were higher than 0.9995, and the detection limits of elements were between 0.00005% and 0.0004%. The recoveries were between 90.0% and 105% and the relative standard deviations were lower than 2.0%. The operation of this method was simple and rapid, and the results were satisfactory.
