摘要
叙述了在盐酸介质中,用抗坏血酸还原铁,以二安替吡啉甲烷作显色剂,水作参比测定钛矿中的二氧化钛。此法适用于二氧化钛含量小于20.00％;操作简便、快速、准确、灵敏度高、选择性好,能满足日常生产快速分析的需要,可代替传统的铝还原—硫酸高铁滴定法。
In the medium of hydrochloric acid, the titania in Ti ore can be determined by using ascorbic acid as reduction of Fe, methane as developer and water as comparison.The method is simple, rapid and precise with high sensitivity and good selection for determinating ore with titania less than 20% . It can meet the demand of the production and substitute the traditional titration method with Al reducting Fe3+ SO4.
