摘　　要：以马来酸酐(MA)、2-丙烯酰胺-2-甲基丙磺酸(AMPS)为原料合成了一种绿色阻垢缓蚀剂聚环氧琥珀酸衍生物(PESA/AMPS),利用EDTA滴定法和分光光度法测定Ca^(2+)浓度,考察了其对CaCO_(3)和Ca_(3)(PO_(4))_(2)的阻垢性能,利用扫描电镜(SEM)研究其阻垢原理,极化曲线研究其缓蚀机理。A green scale inhibitor and corrosion inhibitor PESA derivative(PESA/AMPS)was synthesized from the reactants of maleic anhydride(MA),2-acrylamide 2-methyl-propanesulfonic acid(AMPS).Ca^(2+)concentration was determined by EDTA titration and spectrophotometry,and the ability of inhibiting scale of CaCO_(3) and Ca_(3)(PO_(4))_(2) was investigated.The mechanism of scale and corrosion inhibition was studied by means of scanning electron microscope(SEM)and polarization curve.
