中文摘要：

以丙烯酸（AA）、淀粉（CTS）和腐植酸（HA）为原料，N，N’-二亚甲基双丙烯酰胺（MBA）为交联剂，过硫酸铵（APS）为引发剂，采用水溶液法合成了不同HA含量的AA—CTS—HAZ元共聚吸水树脂。最佳的实验条件为：APS用量占AA质量的3％，MBA用量占AA质量的0．375％，AA中和度为60％，AA单体浓度为1．62mol／L，反应温度为80℃，反应时间为2h。在最佳实验条件下，当HA用量占AA质量的75％时合成的树脂在去离子水中的吸液率为530g／g，在质量分数为0．9％的NaCl溶液中的吸液率为43g/g。

英文摘要：

A series of acrylic acid （AA）-starch （CTS）-humic acid （HA） terpolymerized absorbent resin with different HA content were synthesized from AA, CTS and HA by aqueous polymerization with N,N＇ - methylenebisacrylamide （MBA） as crosslinker and ammonium persulfate （APS） as initiator. The optimal experimental conditions were as follows： the content of APS and MBA accounted for 3%, 0.375% of the mass of AA, respectively; the neutralization degree of AA was 60%; the concentration of AA was 1.62 mol/L; the reaction temperature was 80℃ and the reaction time was 2 h. Under the above experimental conditions, the resin prepared when the mass of HA accounted for 75% of that of AA had absorbency of 530 g/g in deionized water and 43 g/g in NaC1 solution with mass fraction of 0.9%.
