摘要
实验采用浓磷硫混酸加热分解矿样,用铝片还原四价钛,再用三氯化铁标液滴定测定二氧化钛的含量,分析结果表明该方法具有较好的准确度,能满足分析要求,是一种快速、低耗、能大批量分析测定的方法。
The sample was dissolved by heating in the mixture of phosphoric acid and sulfuric acid with high concentration, then titanic was reduced by using piece of metal aluminium, and the titanic oxide was titrated with ironic chloride standardization to determine the content of titanic oxide. The result shows that this analytical method has high accuracy. It is fast in speed, low in consumption, especially for the array sample determination. The result is acceptable.
