• Abstract: 本文以含有强亲水和耐盐基团的2-丙烯酰胺基-2-甲基-1-丙烷磺酸（AMPS）和羧甲基纤维素（CMC）为改性剂，采用水溶液聚合法，制备了改性丙烯酸高吸水树脂，其在去离子水和生理盐水中的吸液倍率分别从改性前的1496g/g和129g/g提高到2944g/g和275g/g，对土壤浸出液的吸收倍率为267.3g/g。同时，该吸水树脂用于豆类植物的种植研究发现，使用改性吸水树脂的土壤能提高绿豆发芽率，并且延长它的存活时间，土埋20天后，该吸水树脂能降解，在38℃，纤维素酶作用6h，改性丙烯酸树脂降解76%。由此可见，改性提高了丙烯酸吸水树脂的吸液能力、耐盐性能和降解性能，该吸水树脂作为土壤保水剂使用，能改良土壤环境，节约农业用水，帮助农业发展，具有重要的社会价值和环境意义。
• The modified acrylic super absorbent resin was prepared by aqueous solution polymerization with 2-acrylamide-2-methyl-1-propane sulfonic acid (AMPS) and carboxymethyl cellulose (CMC) containing strong hydrophilic and salt tolerant groups as modifiers. the absorption ratio of the prepared resin in deionized water and normal saline increased from 1496 g/g and 129 g/g before modification to 2944 g/g and 275g / g respectively, and the absorption ratio of soil leaching solution was 267.3 g/g. At the same time, the study on the application of the water absorbent resin in the planting of legumes found that the soil using the modified water absorbent resin can improve the germination rate of mung beans and soybeans and prolong its survival time. After 20 days of soil burial, the water absorbent resin can be degraded. At 38 ℃ , the modified acrylic resin can be degraded by 76% under the action of cellulase for 6 hours. It can be seen that the modification improves the liquid absorption capacity, salt resistance and degradation performance of acrylic water absorbent resin. As a soil water retaining agent, the water absorbent resin can improve the soil environment, save agricultural water and help agricultural development. It has important social value and environmental significance.
