| 英文摘要 | Superabsorbents used in agricultural and ecological projects with low-cost, slow-release fertilizers and environmentally friendly characteristics have been extensively studied. the use of a natural polymer as the matrix and then further polymerization with some functional material has become the preferred method. in this work, with natural guar gum (gg), partially neutralized acrylic acid, and sodium humate (sh) as the raw materials, ammonium persulfate as the initiator, and n,n'-methylenebisacrylamide (mba) as the crosslinker, gg-g-poly(sodium acrylate) (pnaa)/sh superabsorbents were synthesized through a solution polymerization reaction and were characterized with fourier transform infrared spectroscopy, scanning electron microscopy, and thermogravimetric analysis. the effects of the sh content and mba concentration on the water absorbency were investigated. the results showed that the introduction of sh into the gg-g-pnaa system could improve the water absorbency, swelling rate, ph-resistant property, and reswelling capability, and the superabsorbent containing 15 wt % sh had the highest water absorbency of 532 g/g of sample in distilled water and 62 g/g of sample in a 0.9 wt %, nacl solution. the slow release in water and water retention in sandy soil tests revealed that the superabsorbent could act as a fertilizer as well as an effective water-saving material for agricultural applications.
