摘      要：A procedure was developed for the determination of residual monomers in polycarboxylate superplasticizer （PCs） by reversed-phase high performance liquid chromatography （RP-HPLC）.Four kinds of residual monomers were well separated and determined on a SinoChrom ODS-BP （C18） column with mobile phases composed of acetonitrile and phosphate buffer *** monomers were detected by UV detector at 205 nm and quantitatively analyzed with an external standard *** those residual monomers,the linear response ranged from 4.0×10-6 mol·L-1 to 2.0×10-3 mol·*** determination limit of acrylic acid,sodium methylallyl sulfonate and 2-Acrylamido-2-methylpropane sulfonic acid was 0.02×10-5 mol·L-1,while that of methoxy-polyethylene glycol monoacrylate was 0.1×10-5 mol·*** relative standard deviation （RSD） of high concentration samples was less than 1%,while that of the low concentration samples was between 1%-4%.The standard （additional） recovery ratio was 97.4% -104.2%.
