近年来金属锆及其合金获得很多重要的用途。由於锆的“吸收热中子断面”特别小(0.22~0.4,10~(-24)厘米~2·原子),因此金属锆在原子能工业上用作为核子反应器的结构材料。目前世界各国正紧张地进行锆的研究,锆的地位已愈来愈重要了;也正由於这种关系,锆的分析化学也跟着发展起来。锆的定量方法已经相当多。目前测定锆的常量法,多半用重量法,祇在测定微量锆时用比色法。本文简单地介绍一下各种测定锆的重量法,而着重地介绍苯-[2]-羟基乙酸法。
In recent years, metal zirconium and its alloys have gained many important uses. As zirconium “absorption of thermal neutron cross section” is particularly small (0.22 ~ 0.4,10 ~ (-24) cm ~ 2 atoms), so zirconium metal in the atomic energy industry as a nuclear reactor structural materials. At present, zirconium is being studied intensively by various countries all over the world. The status of zirconium has become more and more important. It is precisely because of this relationship that the analytical chemistry of zirconium has also been developed. Zirconium has a considerable amount of quantitative methods. The current determination of zirconium constant method, most of the gravimetric method, only in the determination of trace zirconium when using colorimetry. This article briefly describes the various gravimetric methods for the determination of zirconium, with a strong emphasis on the benzene- [2] -glycolic acid method.
