这个题目是生产部门提出的,希望能用快速的比色方法代替经常使用的容量法,这样可以适用于分析大批试样,提高工作效率.使磷成为磷钒钼酸铬合物的比色分析方法首先由米伸提出,应用于肥料中磷的测定.威拉德等使用这种方法测定铁矿中的磷.凯特森等研究了各种因素对于这种方法的影响.巴格赫斯特等发现测定钢中的磷时,大量 SO_4~+离子的存在,可使溶液的消光值稳定,不受温度变化的影响.埃勒维尔等用異戊醇萃取后比色测定钢中的磷.在
This topic is proposed by the production department, hoping to use the rapid colorimetric method to replace the often used volumetric method, which can be applied to analyze a large number of samples to improve work efficiency.Phosphorus phosphorus into vanadium molybdate complex colorimetric analysis The method was first proposed by Rice Strenght and applied to the determination of phosphorus in fertilizers.Willard et al used this method to determine the phosphorus in iron ore.Katterson et al studied the influence of various factors on this method.Baghurst et al Found in the determination of phosphorus in steel, the presence of a large number of SO 4 + ions, the extinction of the solution can be stable, independent of temperature changes. Elville and other isoamyl alcohol colorimetric determination of steel after extraction of phosphorus in
