摘要
选用烯丙基磺酸钠(SAS)、苯乙烯磺酸钠(SS)、2-丙烯酰胺基-2-甲基丙磺酸(AMPS)和衣康酸(IA)为单体,与环氧琥珀酸(ESA)分别合成了ESA/SAS、ESA/SS、ESA/AMPS和ESA/IA/AMPS四种含磺酸基团的环氧琥珀酸类共聚物,利用FTIR对共聚物的结构进行了表征,利用SEM对使用不同共聚物时生成的碳酸钙晶型进行了观察。对各种共聚物的阻垢分散性能进行了研究,并与聚环氧琥珀酸(PESA)进行了比较。实验结果表明,4种共聚物中,ESA/IA/AMPS具有全面的水处理性能,在高硬度和高碱度水质条件下表现出优异的阻碳酸钙垢和阻磷酸钙垢性能。当其加药量为40mg/L时,对CaCO_3的阻垢率为82.7%,比PESA提高了10.4%。当加药量为30mg/L时,对Ca_3(PO_4)_2的阻垢率可达100%。同时,ESA/IA/AMPS易于生物降解,14天后可以降解72.7%。电镜分析结果表明,加入共聚物后,垢样中出现了球霰石型碳酸钙,这说明共聚物可以使不稳定相稳定存在,增加了碳酸钙在水中的溶解性和分散性。
Four ESA-polymers containing sulfonic acid groups were synthesized by copolymerization of monomers of epoxysuccinic acid(ESA)and sodium allyl sulfonate(SAS),sodium styrene sulfonate(SS),2-acrylamido-2-methylpropanesulfonic acid(AMPS)and itaconic acid(IA). Their molecule structures were characterized by FTIR spectrum,and the crystalline shapes of the CaCO_3 formed from different polymers were observed by SEM. The scale inhibition and dispersion performances of the polymers were studied and compared with those of PESA. The results showed that the polymer of ESA/IA/AMPS had comprehensive water treatment performances,which showed excellent scale inhibition performances to CaCO_3 and Ca_3(PO_4)_2 in the water of high hardness and alkalinity. When the dosage was 40mg/L,the inhibition rate to CaCO_3 scales was 82.7%,10.4% higher than that of PESA. When the dosage was 30mg/L,the scale inhibition rate to Ca_3(PO_4)_2 reached 100%. Moreover,ESA/IA/AMPS was easy to be biodegraded,and its biodegradation percentage reached 72.7% after 14d.The results of SEM showed that there were vaterite type CaCO_3 in the scales formed in the water samples with the addition of the polymers.This indicated that the polymers could stabilize the unstable phase,and thus enhance the solubility and dispersion of CaCO_3 in water.
