摘要
文章通过实验的方式,研究了几种不同矿石中氧化铝测定方法的应用效果,最后得出研究成果,认为针对于酸溶溶矿样品的氧化铝含量测定,ICP-OES法及DZG93-05EDTA络合醋酸锌容量法测定的效果更为准确可靠,但是当矿石中氧化铝含量低于20%时,ICP-OES法不适用,酸溶法测定更为精准,在普遍性上更有保障值得推广使用。
This paper, by means of experiments to study the application effect of determination method of alumina in several different ore, finally it is concluded that research results, think for acid vast ore samples of aluminum oxide content determination, icp-aes and engage method and edta complexometric DZG93-05 the effect of zinc acetate capacity method is more accurate and reliable, but when the alumina content in the ore is lower than 20%, icp-aes and engage method is not applicable, acid soluble method is more accurate, more secure on the universality of use to be promoted.
