本文利用电位滴定法,测定了弱酸110离子交换树脂的滴定曲线,并提出了改正的Henderson-Hasselbach方程式,按此方程式求得树脂的pK值为4.9。
In this paper, potentiometric titration was used to measure the titration curve of weak acid 110 ion exchange resin. The corrected Henderson-Hasselbach equation was proposed. Based on this equation, the pK value of the resin was 4.9.
