摘要
采用硫氰酸盐示差分光光度法测定高含量的钨 ,取得了较好的效果.方法的回归方程较好 ,相关系数为0.99995;样品回收率为99.3%～100.2% ,RSD为0.28%.
A thiocyanate differential spectrophotonetry method was used to determine the high content tungsten and satisfactory results were obtained.The method's regression equation is good,and the correlation coefficient is0.99995;the recovery is in the range of99.3%～100.2%,and the RSD is0.28%.
