苯酚及其两种衍生物的吸附平衡研究

STUDY ON ADSORPTION EQUILIBRIUM OF\=PHENOL AND TWO TYPES OF ITS DERIVATES

研究了苯酚及其两种衍生物—间甲酚及对氯酚在大孔树脂ＮＫＡ上的吸附平衡，得到了Ｆｒｅｕｎｄｌｉｃｈ及Ｌａｎｇｍｕｉｒ吸附等温式的常数，发现了它们的吸附能力与吸附常数之间的有规律变化关系；通过脱附再生性能的比较，说明了在吸附这３种污染物工艺中，ＮＫＡ与活性炭比较，是更好的吸附剂．

The isotherm parameters for adsorption of phenol, mcresol and pchloroqhenol on resin NKA have been determined with a bottle point isotherm procedure. The results of the experiment show that the order of adsorbility is Pchlorophenol>mcresol>phenol in our experiment conditions.\;Desorbility of phenol and two types of its derivates from NKA is better. So it is a better adsorbent than activated carbon.
