Synthesis of ESA-polymers containing sulfonic acid groups and their performance comparison
摘要
Abstract
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 CaCO3 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 CaCO3 and Ca3(PO4)2 in the water of high hardness and alkalinity. When the dosage was 40mg/L,the inhibition rate to CaCO3 scales was 82.7%,10.4% higher than that of PESA. When the dosage was 30mg/L,the scale inhibition rate to Ca3(PO4)2reached 100%. Moreover, ESA/IA/AMPS was easy to be biodegraded,and its biodegradation percentage reached 72.7% after14d.The results of SEM showed that there were vaterite type CaCO3in 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 CaCO3 in water.关键词
