我们在比色测定钽的显色剂方面作了一些研究,因为目前适用于比色测定的有效试剂还很少。毛主席教导我们:“人类总得不断地总结经验,有所发现,有所发明,有所创造,有所前进”。我们对和甲基紫相类似的一些碱性染料如孔雀绿、罗丹明B、丁基罗丹明B等与氟钽络合物的发色反应进行的对比中,发现孔雀绿有更多的优点,在前人经验的基础上又作了进一步试验和改进,初步建立了孔雀绿比色测定钽的方法。此方法于1962年投入生产以来,分析了几千个样品。正如毛主席的教导:“人的正确思想,只
We have done some research on the colorimetric determination of tantalum because there are not many effective reagents currently available for colorimetric assays. Chairman Mao taught us: ”Man always has to sum up his experience, find something, invent something, create something, and make progress.“ We compared some similar basic dyes with methyl violet, such as malachite green, rhodamine B, butyl rhodamine B, etc., and fluorine tantalum complex color reaction was found, malachite green has more advantages , Based on the experience of predecessors made further tests and improvements, the initial establishment of a method of determination of tantalum green malachite green. Since its introduction in 1962, this method has analyzed thousands of samples. Just as Chairman Mao teaches: ”The correct thinking of man, only
