| 摘 要： | 锆和铪的化学性质非常相似,要用简便方法分离这两个元素是困难的,用化学方法测定微量锆和铪也是困难的。Kouimtzis和Brookes曾经在这方面做了一些工作,在他们工作的基础上,我们确立了实验条件并应用于化探标些中锆、铪的测定。

Fluorimetric Determination of Hafnium in Geochemical Reference Samples with Quercetin |
| |
| Abstract: | The optimum conditions are studied for fluorimetric determination of hafni-
um based on separation with, 743 cation and 717 anion exchange resins. The
exitation wave length and the emission wave length are found to be 401 nm
and 506 nm respectively. The concentration of Hf obeys Beer slaw in the ra-
nge of 0-1 ug/10ml. The recoveries obtained by addition of standard Hf-solu-
tion were 98-108 %. |
