摘要

•A novel floating-separation adsorbent (APHGS-g-P(AMPS)) was designed and synthesized.•APHGS-g-P(AMPS) showed outstanding self-floating separation ability.•APHGS-g-P(AMPS) with satisfactory adsorption capacity was rich in –OH, –NH2 and -SO3-.•The electrophilic addition strategy facilitated the grafting of P(AMPS) polymerized chains.•The sulfonic acid group exhibited excellent universal adsorption for MB and Pb(II).
