A facilely synthesized polyanionic gel adsorbent with high adaptability and new adsorption effects for purification of Cu(II)‐containing wastewater

BACKGROUND Cu(II)‐containing wastewater causes serious pollution of the water environment. Adsorption is one of the most commonly used water purification methods, with the selection of suitable adsorbents being the key factor. This motivates the development of new efficient adsorbents to purify Cu(II)‐containing wastewater. RESULTS A highly adaptable polyanionic gel (PAG) was synthesized by the facile crosslinking copolymerization of acrylic...
