英文摘要	Phosphate control is a crucial environmental issue for responding to the serious eutrophication of water bodies. Development of advanced materials with strong sorption capability and facile preparation are important research areas and orientations. Herein, we offer a green tetra-n-butyl titanate hydrolysis methods by grafting nano-TiO2 gels onto macroporous polymeric ion-exchanger. The process is simple and environment-friendly. The resulting hybrid material exhibits pH-dependent adsorption behaviors with the optimal pH = 4.0-7.0; competitive tests reveal that the obtained composite displays selective sorption behaviors by comparing to its host material in presence of high contents of Cl-, SO42-, and NO3- ions, which is ascribed to the diffusion enhancement by quaternary ammonium groups (N+) within matrix and efficient metal-complexation onto embedded nano-TiO2. Kinetic experiments further demonstrate the accelerated sorption process by N+ induced and the sorption equilibrium is achieved within 100 min, which can be well described by intraparticle diffusion model and pseudo-second-order model. Fixed-bed adsorption further demonstrates the efficient applicability for phosphate sequestration and the exhausted materials can be readily regenerated by alkaline and brine mixtures. All the experimental results indicate that the polymer supported nano-TiO2 is a promising candidate for enhancing phosphate retention in waters.
