Abstract

Abstract:

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). Ca²⁺ concentration was determined by EDTA titration and spectrophotometry, and the ability of inhibiting scale of CaCO₃ and Ca₃(PO₄)₂ was investigated. The mechanism of scale and corrosion inhibition was studied by means of scanning electron microscope (SEM) and polarization curve.

Key words: PESA copolymer, calcium carbonate, calcium phosphate, scale and corrosion inhibition

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Ca²⁺浓度，考察了其对CaCO₃和Ca₃（PO₄）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。
