摘　　要：用三氯化钛-重铬酸钾滴定法测定铁矿石的全铁量,此方法较经典,精密度、准确度均较好。在实际运用中,各实验室根据自身情况,实验条件又略有改变。在不改变其主要原理的前提下,借鉴前人技术,改变传统的样品处理方式,重点对钛的干扰做了研究,同时用铁矿石标准样品对该方法的准确度、精密度等进行验证。试验表明该方法操作简便快速、准确,适用于铁矿石中全铁量的测定。The titanium trichloride potassium dichromate titration method is used to determine the total iron content of iron ore.This method is more classic,with good precision and accuracy.In practical application,each laboratory has slightly changed its experimental conditions based on its own situation.This article,without changing its main principles,draws on previous techniques and changes the traditional sample processing method,focusing on the interference of titanium.At the same time,the accuracy and precision of this method were verified using iron ore standard samples.The experiment shows that the method is simple,fast,accurate,and suitable for the determination of total iron content in iron ore.
