The organic micro-pollutants in the influent and effluent of the CW system and tap water are examined by GC/MS, before analysis the samples are concentrated by C 18 solid phase extraction and then solved by dichloromethane. The results indicate that East Lake is polluted by oil and the PAEs.
The outcomes show that the technique has fairly good applicable prospects on the aspects of sampling collection of river trace organic substance and pretreatment,but it still exits some problems on extension and usage in routine monitoring of water quality and needs a further study and improvement.
The removal of trace organic substances in water such as TOC,UV254,CHCl3,by two of activated carbon fibes(ACF) is studied in the paper,and the both ACF were compared with granular activated carbon(GAC).
On-column preconcentration of trace organic compounds from aqueous media is possible.
Gas chromatography is currently still the most frequently used technique for determining trace organic compounds in environmental samples.
DESI MS enables high-sensitivity detection of trace organic compounds.
A fiber-packed needle was developed as a novel extraction device for gas-chromatographic analysis of trace organic compounds in aqueous samples.
Upon successful optimization of the extraction conditions, a rapid extraction of trace organic compounds from an aqueous sample matrix was successfully demonstrated, where each extraction process was completed within 10?min.
