摘要
用常规的碘量法测定维生素C时存在重复性差、误差较大、浓度过高等问题。针对其问题经过多次实验研究,提出了反滴定法。试验证明此法切实可行,比滴定法测定维生素C更准确,具有一定的实践意义。
There are some problems when using iodometry to measure vitamin C, such as inappropriateness of density, inability of repetition, large error and so on. In view of this situation, the new meehod of anti-titration was put forward to measure vitamin C. It was proved to be more accurate than the method of titration and might be used practically.
