摘要： 有关多元混配胶溶络合物显色体系的研究和应用已有报导^[1-4].作者对Ti(1V)-BPR-Phen-CTMAB混配胶溶络合物的显色反应进行了研究,实验表明,该显色体系对钛(Ⅳ)的测定具有高选择性,并用铝合金和镍合金试样进行本法考验,结果满意。

Abstract: Acolour reaction of a quaternary complex formed titanium with bromopyrogallol red (BPR),1,10-phenanthroline,cetyltrimethylarnmonium bromide (CTMAB) has been studied spectrophotometrically.Asimple and rapid method for determination of titanium(Ⅳ) is proposed.The results show that in the buffer soultion of hydrochloric acid and potassuim biphthalate at pH2.5 titanium (Ⅳ) with BPR-Phen-CTMABcan form a violet quaternary complex,λ_max 625,ε 6.58×10⁴.The composition ratio of Ti(Ⅳ): BPR: Phen: CTMABis 1:2:1:4 by metheds of molaratio and con-tiueous variation and slope ratio
