摘要: A simple and quantitatively reliable method for determination of amine speciation is introduced. The employs three experimental methods that should be readily accessible. results CO2 loaded aqueous solutions 30 wt % monoethanolamine (MEA) are used demonstration the show promising agreement with more complicated spectroscopic reported in literature. measurements were done at ambient temperature atmospheric pressure, since theoretical calculations data from open literature revealed no considerable difference different temperatures. procedure based on acid base titration solution along total loading. quantitative species concentration example MEA other available methods, mainly NMR, particularly free amine, carbamate, protonated concentrations.
