Water contamination caused by dye, paper, textile, and plastics industries has been received more attention, since most heavy metal are harmful to human being and environments. Currently, much attention has been paid to the removal of harmful materials from industrial wastewater. Lot of approaches have been reported to remove them from wastewater, e.g., biological treatment, chemical technologies (e.g. oxidation, and catalytic degradation) and physical methods such as adsorption and membrane filtration. Among them, adsorption has been attracting great attention in the field of heavy metal removal due to its simple and generally low cost, high adsorption efficiency, ease of handling and availability of various adsorbent materials. In this study, acrylic acid was grafted onto polypropylene (PP-g-AAc) using electron beam irradiation. Next, the prepared PP-g-AAc was surface-modified with a material having a catechol group to produce an adsorbent effective for adsorbing harmful substances. |
