- 中文摘要: This study describes preparation of polymeric sorbent and its use in removal of some phenolic compounds from aqueous solution. The polymer [poly(ethylene glycol dimethacrylate - co-methacrylic acid)] is stable both thermally and chemically. High temperature (200 °C) and strong acidic or alkaline solutions (4 M HCl or NaOH) are not effective on the adsorption characteristics of polymer. Removal process of phenols is pH-dependent and from the obtained results pH = 7.0 was selected as an optimum pH. Different parameters affecting sorption process were tested, and it was found that the kinetic of sorption is fast; therefore, column experiment at higher flow rates or batch experiment can be used. Methanol was selected as a washing solvent in column experiments. Capacity of sorbent for the studied compounds was tested and the following order was obtained: p-chlorophenol > p-aminophenol > phenol.
