摘要
采用电位滴定法测定柠檬酸钠的含量,以高氯酸溶液非水滴定柠檬酸钠测定电位差,用二级微商法处理来确定反应终点,从而提高柠檬酸钠含量测定的精密度。
The content of sodium citrate was determined by potentiometric titration method potential difference was obtained by non aqueous titration sodium citrate with perchloric acid .The end point was determined by using second derivative method and the accuracy of determining the content of sodium citrate was improved.
