摘要
本文以P350(甲基膦酸二甲庚酯)为固定相,硅胶为载体,用萃取色谱法分离了钨(Ⅳ)和钼(Ⅳ)。以3.0mol/L HCl-1.0mol/L MgCl_2-1％Tar混合溶液淋洗杂质元素,用1.0mol/L HCl-1.0mol/L MgCl-1％Tar混合溶液和3％Tar溶液分步洗脱钨和钼,获得了良好的定量分离结果,并成功地应用于合金钢及矿物分析。
Tungsten(Ⅵ) and molybdenum(Ⅵ)are separated by extraction chromatography with di(1-methylheptyl)methyl-phosphonate(P350)as a stationaiy phase and silica gel as supporter. The disturbance ions were eluted with a mixture solution of 3.Omol/L HCl-1.0 mol/L MgCl_2-1% tartaric acid(Tar), and then W and Mo were eluted with a mixturesolution of 1.Omol/L HCl-1. Omol/L MgCl_2 -1% Tar and a solution of 3% Tar, respcctively This method has been successfully used in alloy steel and ore analysis.
