Determination of arylamine compounds in waste water using solid-phase extraction and reversed-phase high performance liquid chromatography
1998
A simple, rapid and sensitive method for determining 10 arylamine compounds in wastewater sample using solid-phase extraction (SPE) and high performance liquid chromatography (HPLC) with UV detection is developed. An SPE procedure is described for extracting and preconcentrating the arylamines on Sep-Pak C18 cartridges with methanol as solvent. A mobile phase gradient of acetonitrile-water was used for the separation and determination of the arylamines. The detection limits of the compounds were in the range of 0.1-1.5 mu g/L. Recoveries were 84-107% for 10 arylamines at concentration levels of 20 mu g/L with relative standard deviations of less than 8% (n = 4). (C) 1997 Published by Elsevier Science Ltd.
