摘要
在2.0mol/L左右的盐酸介质中,通过考察共存离子、显色酸度、显色时间、显色剂用量等因素的影响,建立了二安替比林甲烷光度法测定高碳铬铁中微量钛的分析方法。这种方法能够准确、快速地测定高碳铬铁中的微量钛。
The analysis method of measuring and determinating trace titanium in high carbon ferrochrome by diantipyryl methane photometric method is established in about 2.0 mol/L hydrochloric acid, through observing the influence of factors of coexist ion, color-developing acidity, developing time and developer dosage. The method can measure and determinate trace titanium accurately and rapidly (titanium mass fraction: 0.1-0.5﹪).
