Polymer Adsorbent with High Adsorption Capacity under High Salt Concentration
Water pollution is a serious problem on a global scale, and it is required to develop environmentally friendly technologies for the recovery and removal of pollutants with low energy consumption and without the use of large amounts of chemicals. One method of wastewater treatment is to remove pollutants using adsorbents. However, existing adsorbents have a problem that their adsorption capacity is lost due to the Debye shielding effect caused by salts contained in wastewater. The present invention relates to a novel adsorbent consisting of a copolymer of a monomer containing a cationic or anionic functional group and a monomer containing an aromatic group, which exhibits good adsorption performance even in wastewater with a high salt concentration. By using this adsorbent, it is expected to more efficiently and inexpensively remove chemical substances in industrial wastewater, especially ionic dyes contained in wastewater from textile dyeing factories, ink factories, etc.
