本文研究了锆-EDTA-(口底)唑混配型络合物的显色条件,表明在pH5.6—6.6形成了Zr(Ⅳ):EDTA:(口底)唑=1:1:1的稳定络合物,ε=2.81×10~4(λ_(max)=503nm);锆在0—50微克/25毫升遵守比耳定律。并测定了镍基高温合金及铝镁合金中的微量锆,得到了满意的结果。
In this paper, the conditions for the color development of zirconium-EDTA- (mouth-bottom) azole mixed complex were studied. It was found that Zr (Ⅳ): EDTA: (bottom) oxazole = 1: 1: 1 Ε = 2.81 × 10 ~ 4 (λ max (max) = 503 nm); Beer’s law is obeyed at 0-50 μg / 25 ml for zirconium. And the determination of the nickel-based superalloy and aluminum-magnesium alloy trace zirconium, satisfactory results have been obtained.
