• 摘要： 本文以含有強親水和耐鹽基團的2-丙烯酰胺基-2-甲基-1-丙烷磺酸（AMPS）和羧甲基纖維素（CMC）為改性劑，采用水溶液聚合法，制備了改性丙烯酸高吸水樹脂，其在去離子水和生理鹽水中的吸液倍率分別從改性前的1496g/g和129g/g提高到2944g/g和275g/g，對土壤浸出液的吸收倍率為267.3g/g。同時，該吸水樹脂用于豆類植物的種植研究發現，使用改性吸水樹脂的土壤能提高綠豆發芽率，并且延長它的存活時間，土埋20天后，該吸水樹脂能降解，在38℃，纖維素酶作用6h，改性丙烯酸樹脂降解76%。由此可見，改性提高了丙烯酸吸水樹脂的吸液能力、耐鹽性能和降解性能，該吸水樹脂作為土壤保水劑使用，能改良土壤環境，節約農業用水，幫助農業發展，具有重要的社會價值和環境意義。
• 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.
