前言目前硅酸盐的系統分析Fe、Al和Ti的合量,一般采用EDTA容量法,而Ti用比色法测定,由AlTi合量减去Ti的量得Al的量。和著的「絡合滴定法测定合金中Ti」一文中,指出Ti和H_2O_2絡合物在高酸度的情况下能和EDTA定量地形成牢固的絡合物,据此作者对硅酸盐中Ti的分析作了試驗,虽然含Ti量較低,但也能得到滿意的結果,这就使硅酸盐分析中Ti的測定以容量法解决,提高了分析速度。 Preface At present, silicate system analysis Fe, Al and Ti combined amount, generally using the EDTA volumetric method, and Ti by colorimetric method, from the amount of AlTi minus the amount of Ti Al amount. In his article titled “Determination of Ti in Alloy by Complexometric Titration”, it is pointed out that Ti and H 2 O 2 complexes can form strong complexes with EDTA quantitatively under high acidity. Therefore, Of the analysis was tested, although the lower the amount of Ti, but also get satisfactory results, which makes the determination of silicate in the determination of Ti volumetric method to improve the analysis speed.
