| 摘 要： | 采用静态法测定了5种树脂对碳酸氢钾溶液中甲酸的交换吸附量，其中，D293强碱性阴离子交换树脂具有最高的交换吸附量，考察了温度对D293树脂交换吸附量的影响。在30℃条件下，利用静态法测定了甲酸在D293树脂上的吸附等温线，在低的甲酸浓度范围内，Langmuir方程比Freundlich方程能更好地描述树脂对甲酸的吸附；同时，测定了甲酸在D293树脂上的穿透曲线。

| Abstract: | The exchange and adsorption properties of formic acid with five types of resins were studied. Among them, strongly basic anion exchange resin D293 can provide the highest exchange capacity of formic acid. The influence of temperature was also studied. Exchange isotherm curve of formic acid on D293 resin at 30℃ was studied, and the Langmuir equation can explain the exchange equilibrium curve of formic acid on D293 resin better than the Freundlich equation. The breakthrough curve of formic acid on D293 resin was also determined. |
