The use of solid phase microextraction technique for the extraction of trihalomethanes in drinking water

Solid phase micro-extraction technique is a fast, sensitive, inexpensive, portable and solvent free method for extracting organic compounds from aqueous samples. This technique involves exposing a fused silica fibre that has been coated with a stationary phase to an aqueous solution containing organ...
