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.
