摘要

A novel poly(ethylene glycol)-based nanocomposite hydrogels containing Fe-octacarboxylic acid phthalocyanine (FeOCAP)/magnetic attapulgite was successfully synthesized by in situ polymerization. Fourier transform infrared spectroscopy result showed the FeOCAP/magnetic attapulgite was successfully introduced into the hydrogels matrix. Besides, the hydrogen bond interactions existed between FeOCAP/attapulgite and hydrogels, which acted as the crosslink points in the hydrogels network, and meanwhile, stabilized the nanoparticles in hydrogel without phase separation. Photocatalytic activity studies confirmed that the as-prepared nanocomposite hydrogels had excellent photocatalytic activity for rhodamine B photodegradation, as compared to the pure hygrogels. The rhodamine B removal percentage of the hydrogels could reach nearly 100% and the kinetics of photocatalytic degradation reaction was described by the Langmuir-Hinshelwood kinetics models. The hydrogels could be reused more than five times without losing any photodegradation ability, which indicated that the hydrogels would be potentially useful in dyes wastewater treatments.
