摘要
详细地研究了用硫氰酸盐光度法测定钨基试样中钼量的方法。采用过氧化钠分解试样后,干过滤使铁、锰等与钨钼分离,用柠檬酸络合钨,于约1 1mol/L的硫酸介质中,以铜盐为催化剂,硫脲为还原剂,用硫氰酸盐光度法测定钼量。分析结果令人满意。
The sample is decomposed with sodium superoxide,than to separate iron and manganese from tungsten and molybdenum.After complexing the tungsten with citric acid,the molybdenum content is determined in about 1 1 mol/L sulfuric acid with thiocyanate spectrometric method using copper salt as catalyst and sulfocarbamide as reductant.The analytical results are satisfactoty.
