| 摘 要： | 本文对高钛渣中低价钛的测定方法进行了研究,文中采用FeCl_3—HCl分离除去M_(Fe),Fe_2O_3及部份FeO,残渣以H_2SO_4—HF—H_3PO_4溶解,用硫酸高铁铵氧化低价钛,然后用K_2Cr_2O_7标准溶液滴定生成的Fe~(2+),本方法具有简便、快速、重现性好的优点,适用于日常分析。

| Abstract: | In this article a method is investigated for the determination of low-valence titanium in slag containing a high titanium content. The residue is dissolved using H2SO4-HF-H3PO4 after tMFe, Fe2O3 and the part of FeO are separated from sample with FeCl3-HCl, and NH4 Fe(SO4)2 is added to oxidate low titanium. Then the standard solution of K2Cr2O7 is used to tit-rat Fe2+ in sample solution. The method possesed with a advantage of simple rapid and good repeatability so that it can be used in the roution determination. |
