【 摘 要 】

The simple and easy performed automated method for the IR determination of petroleum products (PP) in water using extraction-chromatographic cartridges has been developed. The method assumes two stages: on-site extraction of PP during a sampling by using extraction-chromatographic cartridges and subsequent determination of the extracted PP using sequential injection analysis (SIA) with IR detection. The appropriate experimental conditions for extraction of the dissolved in water PP and for automated SIA procedure were investigated. The calibration plot constructed using the developed procedure was linear in the range of 3-200 mu g L-1. The limit of detection (LOD), calculated from a blank test based on 3 sigma was 1 mu g L-1. The sample volume was 1 L. The system throughput was found to be 12 h(-1). (C) 2015 Elsevier B.V. All rights reserved.
