摘要
通过条件实验,确定了电感耦合等离子体-原子发射光谱同时测定铝合金中钴和镍的工作条件,通过基体匹配和背景校正,消除了基体和光谱干扰;建立了电感耦合等离子体-原子发射光谱同时测定铝合金中钴、镍的方法;方法检出限为钴1.25μg/L、镍3.00μg/L,相对标准偏差为钴0.32%、镍0.55%,回收率为钴82.84%—103.4%、镍88.50%—109.0%,该方法简便、快速、检出限低、干扰小、准确可靠,可用于铝合金中钴、镍的同时测定。
Operating parameters of inductively coupled plasma atomic emission spectrometry （ICP-AES） were selected through, parameter experiment. Matrix interference and spectrum interference were eliminated through matrix match and background correction. A method for simultaneous determination of Co and Ni in aluminium alloy by ICP-AES was established. The detection limit of the method was 1. 25ug/L for Co and 3. 00ug/L for Ni, the relative standard difference （RSD） was 0. 32% for Co and 0.55% for Ni. The method recovery rate was 82. 84%-103.4% for Co and 88. 50%--109.0% for Ni. The method was facile, quick, low interferential,accurate and reliable. It could be applied to simultaneous determination of Co and Ni in aluminium alloy.
