近年来钨的分光光度法已有不少专论,一般以硫氰酸盐光度法居多,以邻苯二酚类试剂与碱性染料测钨亦可获得较高灵敏度。但就三元络合物测钨而论,多因钼等离子的干扰,影响选择性,须经繁杂的分离,因而使方法难于应用。 Tungsten spectrophotometry in recent years, there have been many monographs, most of the majority of thiocyanate spectrophotometry, catechol reagents and alkaline dyes measured tungsten can also get higher sensitivity. However, ternary complexes measured tungsten, mostly due to the interference of molybdenum plasma, affecting selectivity, subject to complicated separation, making the method difficult to apply.
