前言钛铁中钛的测定,一般采用氧化-还原方法,由于Ti~(+3)易被空气氧化,所以需用惰性气体保护,操作比较繁杂,不易掌握。络合滴定的发展,使合金中钛的测定和硅酸盐中钛的测定有所进展,但对黑色金属来说,还未见到这方面的报导。陈永兆介绍乳酸是钛的良好掩蔽剂,因而乳酸也是Ti-EDTA络合物的良好释放剂,根据此,作者对钛铁做了试验,并做了钛铁中常见元素铝等对分析钛的影响试验,比较满意的解决了钛铁中钛铝的测定,改善了操作条件,提高了分析速度。
Preface Titanium titanium in titanium iron determination, the general use of oxidation - reduction method, due to Ti ~ (+3) is easily oxidized by air, so the need to use inert gas protection, the operation is more complicated and difficult to grasp. The development of complexation titration, titanium alloy in the determination of titanium and silicate determination of the progress, but the ferrous metals, has not yet seen this report. Chen Yongzhao Introduction Lactic acid is a good masking agent for titanium, and therefore lactic acid is also a good release agent for Ti-EDTA complexes. Based on this, the authors tested the titanium iron and made the analysis of titanium, a common element of titanium iron, Test, more satisfactory solution to the determination of titanium and titanium in aluminum and aluminum to improve the operating conditions and improve the analysis speed.
