【摘要】 本文研究了自制的吸附剂对苯酚、 4 氯酚、 2 4 二氯酚和五氯酚钠的吸附行为 ,以及pH值和投加量等因素对吸附的影响 .结果表明 ,Freundlich和Langmuir等温线都能够较好地表述这四种酚类化合物的吸附行为 ;在pH 6 5— 7 5 ,投加量为 8g·l- 1 ,振荡平衡后 ,自制的吸附剂对苯酚、 4 氯酚、 2 4 二氯酚和五氯酚钠的去除率可以达到 90 %以上更多还原

【Abstract】 The adsorption behavior of phenolic (phenol,4-chlorophenol,24-dichlorophenol and pentachlorophenol)compounds on the high-performance synthesized sorbent was examined in this study,and the optimal conditions,such as the pH,the mass of the sorbent also were investigated in detail.Freundlich isotherm and Langmuir is otherm were suggested as the appropriate types for these compounds.The high-performance sorbent can adsorb more than 90% of phenol,4-chlorophenol,24-dichlorophenol and pentachlorophenol when the pH range was found to be 6 5-7 5,and the optimum mass of the sorbent was 8g·l -1.更多还原
