以羧甲基纤维素（ CMC ）为基底，通过自由基聚合制备羧甲基纤维素（CMC）／聚乙二醇（PEG）／聚丙烯酸（PAA）高吸水性树脂。研究该树脂对蒸馏水、雨水和NaCl溶液的吸水性。实验结果表明：蒸馏水、雨水和0.2 mol／L NaCl溶液中对应的溶胀比分别为680g／g、520g／g和130g／g。离子强度由0增加到0.2 mol／L，溶胀比由680 g／g减小到130 g／g。随着pH值增大，溶胀比逐渐增大，在pH＝8.4时发生突增，溶胀比达到最大值1057 g／g。
以羧甲基纖維素（ CMC ）為基底，通過自由基聚閤製備羧甲基纖維素（CMC）／聚乙二醇（PEG）／聚丙烯痠（PAA）高吸水性樹脂。研究該樹脂對蒸餾水、雨水和NaCl溶液的吸水性。實驗結果錶明：蒸餾水、雨水和0.2 mol／L NaCl溶液中對應的溶脹比分彆為680g／g、520g／g和130g／g。離子彊度由0增加到0.2 mol／L，溶脹比由680 g／g減小到130 g／g。隨著pH值增大，溶脹比逐漸增大，在pH＝8.4時髮生突增，溶脹比達到最大值1057 g／g。

Carboxymethyl cellulose/poly(ethylene glycol)/poly(acrylic acid) superabsorbent composite were synthesized by free radical polymerization. The water absorption for distilled water, rainwater and NaCl solution were investigated. The results showed that the swelling ratio for distilled water, rainwater and NaCl solution were 680, 520 and 130 g/g, respectively. The swelling ratio decreased dramatically from 680 to 130 g/g as ionic strength increased from 0 to 0. 2 mol/L. Moreover, with increasing of pH values, the swelling ratio increased gradudlly, and it showed a characteristic increase at pH=8. 4. The maximum swelling ratio was 1057 g/g.
