基于富马酸、富马酸一钠、富马酸二钠在无水乙醇中溶解度的差异,探讨了用离子交换-酸碱滴定法测定富马酸及其钠盐混合物各组分含量的方法。
Based on the difference of the solubility of fumaric acid, monosodium fumarate and disodium fumarate in absolute ethanol, the method for determining the content of fumaric acid and its sodium salt mixture by ion exchange-acid-base titration was discussed .
