摘要
所述的FIA法测定钢铁中钼是基于硫氰酸钼分光光度法.试样经王水溶解后,加硫磷混酸发烟来控制试样的酸度,并对Fe^(3+)的还原,发色酸度,试剂浓度,共存元素影响做了试验.本法可测定各种钢铁中0.1～2%的钼,每小时可测60个样.
A flow injection procedure is proposed for the determination of Mo in steels, based on the thioc-yanide method.After dissolution of the steel sample in agua regia, acidity can be controlled by the addition of H2SO4-HgPO4 (1+1) , the sample soluion is evaporated to white fumes of H2SO4.
Mo in various steel samples can be determinated in the range of 0.1-2%, at a rate of up to 60 samples per hour.
