A novel amphoteric copolymer flocculant was synthesized by incorporating a cationic moiety 2,3-epoxypropyl trimethyl ammonium chloride (GTA) and an anion moiety phosphate onto the backbone of starch with microwave radiation. The synthesized starch copolymer was characterized and examined by FTIR, (1)H NMR spectroscopy, scanning electron microscopy (SEM),(More)
Novel hierarchical microspherical BiOI photocatalysts modified by graphene-analogue BN were prepared by a facile one-pot solvo-thermal method. Rhodamine B, methylene blue and 4-chlorophenol were used as target pollutants to evaluate the photocatalytic performance of the BN/BiOI composites under visible light irradiation. The experimental results indicated(More)
Instability of superwetting surface is the stumbling block of flexible polymeric membranes for continuous separation of water-in-oil or oil-in-water emulsions. Manipulation of rigid superwetting nano-TiO2 on hierarchical poly(vinylidene fluoride) (PVDF) membrane by mimicking the plant roots holding soil behaviour enabled the generation of robust(More)
