Title
Separation and Radiocarbon Analysis of Environmental Chloroacetates: Environmental Sources of Chloroacetates by Preparative Capi,Used
Delivery time: 8-12 business days (International)
The origins of individual organic pollutants in the atmosphere are of considerable interest, on the local scale for identifying pollution sources, and on the global scale because of potential effects on climate. Like many environmental pollutants the sources of chloroacetates are still not clearly identified. A method had been developed for quantifying biogenic contribution in environmental chloroacetates by radiocarbon analysis using offline preparative capillary gas chromatography/ accelerator mass spectrometry (PCGC/AMS). 14CContaining standards were synthesized. A method for isolation of chloroacetates from largevolume rain water and air samples and their preparation for PCGC separation was developed and optimized. Complete chromatographic resolution of the complex rain water extract can be achieved by two dimensional PCGC separation on two columns with different polarities, on a nonpolar column, cryogenic trapping and further separation on a polar column gave pure chloroacetates. AMSmeasurements of old and modern chloroacetate standards are done for calibration.
