| Abstract: | This paper reported a method to determine the trace amount acrylamide in water by joint utilization of solid phase micro-extraction and pressurized capillary electrochromatography(SPME-pCEC).The acrylamide was extracted from sample by adsorbed on active carbon and then eluted off with methanol.The extraction has a stable recovery ratio of 59.0% for a wide range of concentration over than three orders of magnitudes.Thus the concentration of acrylamide could be enriched for about sixty multiples while the cubage ratio of sample to eluate is 100.The eluate was then analyzed by a pressurized capillary electrochromatogrameter with an UV-visible detector.The linear response range of this method extended downward to 5ng/g with the excellent linear regression coefficient of 0.999. |
