摘要
对椰壳载金炭样品采用不同K值缩分法进行制样,按切乔特缩分公式进行缩分,加工制备-200目样品。采用原子吸收法对样品进行分析,计算出样品的平均含量和平均偏差,确定缩分系数K值为0.1。为载金炭样品加工制样,缩分系数K值的选择,提供了相应的依据。
Division methods with different K value are used for sample preparation of gold-bearing coconut shell carbon.Samples are divided according to the Qeqott formula and processed into samples of-200 mesh.FAAS is applied to analyze the samples and the average content and derivation are calculated,determining the division K value as 0.1.The process provides references for the sample preparation of gold-bearing carbon and the selection of division K value.
