铁钛合金中所有测定钛的方法,不但费时,而且操作必须特别谨慎。在乌沙菁柯及别克莱校娃尔氏的论文中(Ю·И·уса-тенкоиТ.Е.Беклешова,Зав.Лаб.21,779(1955)曾指出:在一定的条件下,钢铁试剂(Cupferon)很易旋转铂微电极上氧化而产生明显的扩散电流,其波的高度与铜铁试剂的浓度成正比。故建议对于那些能与铜铁试剂生成不溶性的沉淀或稳定络合物的元素,可用铜铁试剂作滴定剂以进行安培滴定。在进行了一系列的实验后,确定了使铁结合成EDTA的络合物时,溶液的酸度以在0.15N到0.5N之间为宜。此时纵然铁的含量六倍于钛,铁的影响仍能消除。在铁钛合金中铁和钛的比例往往就是如此,因此可以作为制订快速而精确的测定铁钛合金中钛的根据。
All methods of determining titanium in iron-titanium alloys are not only time consuming but also must be handled with extreme care. It has been pointed out in the paper of Usasper Kohl and Becker Klein School (Ю · И · уса-тенкоиТ.Е.Беклешова, Зав.Лаб.21,779 (1955) that under certain conditions, the cupferon It is easy to rotate the oxidation of platinum microelectrode to produce a significant diffusion current, the wave height is proportional to the concentration of copper and iron reagents.It is recommended for those who can with the copper and iron reagents insoluble precipitates or stable complexes of elements available After a series of experiments, it has been determined that when the iron is incorporated into the EDTA complex, the acidity of the solution is preferably between 0.15 N and 0.5 N. At this point Even though the iron content is six times that of titanium, the effect of iron can still be eliminated, which is often the case for iron-titanium alloys, making it possible to establish a rapid and accurate basis for the determination of titanium in iron-titanium alloys.
