摘要
在钨酸钠溶液中，用草酸代替柠檬酸能掩蔽大量的钨，在显包溶液中降低硫脲浓度，克服溶液混浊，使用硫氰酸盐显色的溶液吸光度稳定、测定结果准确。
Substitution of oxalic acid for citric acid in sodium tungstate solutions permitslarge amounts of tungsten to be masked. By lowering the concentration of sulfourea, thus e-liminating the turbidity of the solution and stabilizing the colored solution the determinationof molvbdenum is improved and proved to be accurate
