摘要
本文研究了钛(Ⅳ)一氯—磺酚S—N—苯甲酰苯基羟肟酸三元混配配合物的形成条件,提出了一个快速简便的分光光度法,用于测定硅酸盐矿物中的微量钛。Ti(Ⅳ)量在0—20μg/25ml符合比尔定律,λ=660nm,ε=1.98×10~4L.mol.cm^(-1)。
A ternary complex of Ti (Ⅳ) with chlorosulfophenol S and N-phenylbenzohydroxamic acid has been studeed. The molar ratio of Ti/CSPS/BPHA is established to be 1∶1∶1. Its maximum absorption is measured at 660 nm with the molar absorptivity of 1.98×10~4. Beer's law is obeyed in the range 0—20μg/25ml for Ti. Titanium in silicates was determined satisfactorily by the proposed method.
