【摘要】 研究了电感耦合等离子体-原子发射光谱法（ICP-AES）测定镍矿中的镁．通过样品处理、酸度确定、谱线及仪器参数选择等试验，使方法操作简便快捷、结果科定、准确度较高．当镍矿中镁的含量分别为2．09％，8.12％和12．16％时，测量相对标准偏差分别为3．30％，1．35％和0．76％．当镁的含量为1．00％～4．00％时，加料回收率为99．5％～100.5％．更多还原

【Abstract】 Determination of Mg in Ni ore by ICP-AES has been studied. After testson the sample treatment, acidity influence, selection of spectrum lines and instrumentparameters, etc., it is found that this method is simple and rapid in operation; results aresteady and accuracy is high. When the Mg contents in Ni ore are 2. 09%, 8.12% and12. 16%, respectively, the relative standard deviations in determination are 3. 30%, 1. 35%and 0. 76%, respectively. When the Mg contents lie between 1. 00%～4. 00%, the additionrecoveries are between 99. 5 % ～100. 5 %.更多还原
