摘　　要：闪锌矿的主要成分是锌(67%)和硫(32%),同时伴生有有色,分散元素要求分析。本文采用阳离子树脂交换分步淋洗,对砷、硒、碲、锗、锌、铜、镉、钴、镍和铁等元素进行分离与测定。在盐酸介质中砷、硒和锗很容易与各种阳离子分离。The test solution in 0.1 N-HCl acidic medium was passed through a colum packed with cation exchange resin,germaninm was oxidized to hexa valent by potassium bichromate in advance.As,Se,Te and Ge were determined in the eluatej after elution with NH_(4)NO_(3)-NH_(4)OH solution,Cu,Zn,Cd,Co and Ni were determined;after elution with 2N-HCl solution,iron was determined.The procedure can be used to determine as many as ten elements by AAS,spectro-photometry,polargraphy and induced colorimetry separately.
