Highly efficient remediation of bisphenols (BPs) contaminated wastewater by adsorption is intriguing but remains challenging. Herein, we present a starch-grafted-styrene hydrophilic porous resin (SGS-HPR) showing excellent BPs adsorption capacity, through simple graft copolymerization and then external knitting strategy. The typical influencing factors of graft copolymerization and external crosslinking processes were investigated systematically. A series of characterization experiments verified the successful fabrication of SGS-HPR and manifested that the optimum product, SGS-HPR7, possesses a hierarchical porous structure with strong hydrophilicity. The abundant presence of starch chain in SGS-HPR7, not only increased the hydrophilicity but also enhanced the adsorption affinity, making SGS-HPR7 exhibit remarkable removal ability toward BPs. The adsorption performance of SGS-HPR7 was studied systematically in static mode. The results showed that SGS-HPR7 can adsorb BPs quickly with a stable ability irresp. of the varying aqueous environments. Besides, the continuous adsorption and regeneration experiments were conducted using bisphenol A (BPA) as the model BPs. The adsorbed BPA can be efficiently desorbed by ethanol elution, and the regenerated SGS-HPR7 showed great recyclability. Interestingly, SGS-HPR7 also retained the superior adsorption capacity and marvelous regeneration ability in the continuous adsorption experiments Further, according to theor. calculation studies, the hydrogen-bonding and π-π stacking interactions involved mechanism was uncovered clearly. Collectively, this work provides a new convenient strategy to fabricate new highly hydrophilic bio-based adsorbent for BPs removal. This study involved multiple reactions and reactants, such as 4,4′-Methylenediphenol (cas: 620-92-8SDS of cas: 620-92-8).
4,4′-Methylenediphenol (cas: 620-92-8) belongs to alcohols. Alcohols are among the most common organic compounds. They are used as sweeteners and in making perfumes, are valuable intermediates in the synthesis of other compounds, and are among the most abundantly produced organic chemicals in industry. The most common reactions of alcohols can be classified as oxidation, dehydration, substitution, esterification, and reactions of alkoxides.SDS of cas: 620-92-8
