光度法测定微量硅,一般多采用硅钼黄法或硅钼兰法,然而这些方法的灵敏度均较低。近年来,以形成碱性染料一杂多酸离子缔合物显色反应为基础的水相测定痕量元素的高灵敏度光度分析法有了迅速的发展,已研究了以硅钼兰-丁基罗丹明B缔合物水相光度法测定合金中的微量硅。在乳化剂OP存在下,结晶紫-硅钼杂多酸缔合物分光光度法、在动物胶存在下,硅钒钼兰-丁基罗
Spectrophotometric determination of trace silicon, the general use of molybdenum silicon molybdenum or silicon molybdenum blue method, however, the sensitivity of these methods are low. In recent years, the high sensitivity photometric method for the determination of trace elements in aqueous phase based on the color reaction of basic dye-heteropoly acid ion complex has been developed rapidly. Determination of Trace Silicon in Alloy by Rhodamine B Association Photometry. In the presence of emulsifier OP, crystal violet - silico-molybdenum heteropoly acid association spectrophotometry, in the presence of animal glue, silicon vanadium molybdenum blue butyl Ding Luo
