| 英文摘要 | a series of novel poly(acrylic acid)/coco peat (paa/cp) superabsorbent composites were prepared via the ultraviolet irradiation copolymerization of acrylic acid monomer (paa) and coco peat cellulose (cp) in the presence of the cross-linker trimethylolpropane trimaleate. the physico-chemical structures of obtained paa/cp were characterized by fourier transform infrared spectroscopy, thermogravimetry/derivative thermogravimetry, x-ray diffraction, and scanning electron microscopy, respectively. the critical parameters of affecting the water absorbency of paa/cp, including the cross-linker level, amount of cp and reaction time, were studied in detailed. the experimental results showed that the paa/cp samples exhibited the maximum swelling value of 523.09g/g in distilled water and 40.52g/g in 0.9wt % nacl solution. the swelling behaviors of paa/cp were significantly relied on the concentration of salt solution and the ph of external solution. the effect of ions species on the swelling performance was in the order: na+>ca2+>fe3+ , and in ph 2.2 and 7.2 aqueous solutions paa/cp composites displayed better ph-responsiveness and reversible on-off switching characteristics. urea, as an agrochemical model, was loaded into paa/cp substrate to supply with nitrogen nutrient. the test of their loading and releasing diffusion performance of urea suggested that the urea loading percentage of paa/cp was remarkably dependent on the concentration of aqueous urea solutions and the release of urea from loaded paa/cp samples in water followed a non-fickian mechanism. owing to their considerable good water absorption capacity, slow urea release, economical and environment-friendly merits, paa/cp composites could be exploited for the agriculture applications. copyright (c) 2016 john wiley & sons, ltd. |
