摘要
Abstract
The inductively coupled plasma atomic emission spectrometry method is established for determination of calcium,magnesium,aluminum,zinc,chromium,lead and manganese in nickel ore concentrate with high aluminum content.The sample is melted by the mixed flux of anhydrous sodium carbonate and sodium peroxide,leaching and acidification of sample is done by hydrochloric acid.The inductively coupled plasma atomic emission spectrometry method is used for determination on the content of seven elements in the test solution under the selected measurement condition.Under the optimal test conditions,The measuring range of calcium,magnesium,aluminum,zinc,chromium,lead and manganese separately is 0.50％ ～ 2.50％,0.50％ ～2.50％,0.50％ ～ 10.00％,0.005％ ～ 1.00％,0.005％ ～ 1.00％,0.005％ ～ 1.00％,0.005％ ～ 1.00％.The precision degree test results show,the relative standard deviation (RSD)of the testing results of each element in sample is less than 7％.关键词
