| 英文摘要 | Traditional superabsorbent polymers have wide application potential as an adsorbent, but the poor physical and mechanical properties limit their further applications. To tentatively overcome this dilemma, a novel poly(acrylic acid)/poly(vinyl alcohol)/yeast superabsorbent polymers (PAA/PVA/yeast SAPs) with interpenetrating polymer networks (IPNs) were fabricated herein via solution polymerization. The mechanical stability tests showed that the resulting products could desirably resist the destruction of shear flow (< 5000 rpm) and load pressure (< 3 kg). The effects of yeast content, pH, contact time, initial dye concentration and temperature were systematically studied to evaluate their adsorption properties. Consecutive five cycles of adsorption-desorption indicated that their easy regeneration and reusability. More importantly, the PVA/PAA/yeast SAPs displayed brilliant pH-dependent selective adsorption for dyes in dye mixtures. It is believed hereby that the PAA/PVA/yeast SAPs can be expected to be economically and technically feasible for the scalable treatment of dyes wastewater. |
