摘要
用拜耳法对铝土矿中的铝进行提炼后,赤泥中铁、铝、钛含量较高,对铝的测定产生干扰。该实验讨论了在铁、钛同存下用滴定法测铝时掩蔽剂乳酸及氟化钠的最佳用量。
When Aluminium has been reduced by Bayer＇s methed from Aluminium mine,the iron and Titanium have been very high in blast fernace slag. They will interface the determination of Aluminium. The concentration of NaF and [CH3CH（OH）COOH] are discussed when the concentration of Aluminium has been determined with the effect of existing iron and Titanium .
