锆的显色剂往往与铪也有颜色反应。日前高温合金锆的光度测定方法中,实际上是通过测定锆铪合量来表示锆的分量,显然对于含铪的高温合金来说,是不能适应分析要求的。锆铪分量的测定,一般都要用离子交换、吸附层析、纸上色层、溶剂萃取等方法预先分离。其中纸上色层法是一种简便而有效的方法。我国地质部门以各种混合有机溶剂作展开剂解决了锆英石中大量锆与小量铪的分离和测定问题。我们用钽试剂萃取法,使锆铪与高温合金中其他元素分离后,吸取广东冶金地质实验研究所的经验,以磷
Zirconium developers often have a color reaction with hafnium. Recently, high-temperature alloy zirconium photometric method, in fact, by measuring the amount of zirconium-hafnium to represent the zirconium component, apparently for hafnium-containing superalloy, it can not meet the analytical requirements. Determination of zirconium hafnium components, generally have to use ion exchange, adsorption chromatography, paper chromatography, solvent extraction methods such as pre-separation. Paper color layer method is a simple and effective method. China’s geological department to a variety of mixed organic solvents as a solvent to solve a large number of zircon zirconium and a small amount of hafnium separation and determination of the problem. We use tantalum reagent extraction method, the zirconium hafnium and high temperature alloy after the separation of other elements, learn from Guangdong Metallurgical Geological Experimental Institute of experience to phosphorus
