程广禄[1]曾报告钼(Ⅳ)在0.1-0.2N高氯酸溶液中与二甲苯酚橙作用呈微红色,反应灵敏度不高。低价钼与二甲苯酚橙的反应似未见报告,作者试验若干种还原剂,提出用盐酸羟胺还原钼,随后用二甲苯酚橙检出钼的方法。本法具颇高的灵敏度和选择性,可在钨和铼存在下检出钼。兹将实验结果报告如下。

In the present paper a method of detecting molybdenum with xylenol orange has been proposed.After being reduced with hydroxylamine hydrochloride in 1.5-2 N HCl or HCIO4 solution,molybdenum reacted with xylenol orange at pH 2-3 and the solution turned to red-purple or orange colour,which confirmed the presence of molybdenum.
