分光光度法测定铟,使用最广泛的显色剂是三苯烷甲碱性染料.许多文献已介绍了孔雀绿、结晶紫、甲基紫、罗丹明、乙基罗丹明、罗丹明6G、丁基罗丹明B等方法测定微量铟.多数资料介绍需经萃取或共沉淀等预分离手续,较为烦锁.本试验选用灵敏度较高的丁基罗丹明B法,针对金属锡的性质 Spectrophotometric determination of indium, the most widely used developer is a terphenyl methyl basic dye.Many literatures have been introduced malachite green, crystal violet, methyl violet, rhodamine, ethylrhodamine, rhodamine 6G, small Determination of trace amounts of indium by the method of rhodamine B, etc. Most of the data are subject to pre-separation procedures such as extraction or coprecipitation, which are more annoying to lock.In this experiment, we selected the butyl rhodamine B method with high sensitivity,
