| 摘 要： | 测定了N503、TBP和TRPO萃取苯酚的平衡曲线。发现TBP和TRPO萃取平衡线可用Langmuir型方程表示,20℃时的萃取平衡常数分别为157和540。N503萃取苯酚的平衡线呈S形,因此低浓度时萃取脱酚比较困难。含TBP和TRPO的萃淋树脂吸附苯酚的平衡性能与萃取相似,其温度引起的变化和溶剂萃取完全相同,但同温度下的平衡常数略小。讨论并比较了不同萃取剂萃取和萃淋树脂吸附的性能,认为萃淋树脂有其优越性。

| Abstract: | The equilibria of extraction of phenol by N503, TBP and TRPO and adsorption of phenol by TBP and TRPO extracting resins were studied respectively and compared. It is difficult to reduce phenol in industrial effluents to 1 ppm by extraction with N503. The extracting resin method may be a attractive alternative to the combined process of extraction and adsorption. Its advantages over extraction consist in very low residual phenol content in treated liquor and simple equipments and over adsorption by activated carbon in high capacity. |
