| 摘 要： | 应用EDTA间接滴定法测定铝土矿、高岭土、黏土等矿石中的三氧化二铝,试验了不同种类的酒石酸掩蔽钛对三氧化二铝测定结果的影响。建议选择左旋体或右旋体酒石酸作掩蔽剂,尽量不要选择内消旋体酒石酸,更不能选择外消旋体酒石酸。采用酒石酸钾钠作掩蔽剂,三氧化二铝的测定结果良好,方法快速、简便。

| Abstract: | A method for the determination of Al2O3 in bauxite, kaoline and clay minerals by EDTA-indirect titrimetry is proposed. The effect of different kinds of tartaric acids as masking agents on determination of Al2O3 was tested. From the experimental results, it suggested that the dextro-isomer and laevo-isomer tartaric acids can be used as masking agents instead of mesomeride tartaric acid and especially raceme tartaric acid. The analytical results of Al2O3 were satisfactory when seignette salt was used as masking agent. The method provides the advantages of more efficiency and simple operation. |
