SPE of Pesticides from Fruit Juices with Carbon Nanotubes

December 1, 2008

A research group from the University of La Laguna and ICIA (both in La Laguna, Tenerife, Canary Islands, Spain) used multiwalled carbon nanotubes as a solid-phase extraction (SPE) medium for extracting eight organophosphorus pesticides from various commercial apple, grape, orange, and pineapple juices.

A research group from the University of La Laguna and ICIA (both in La Laguna, Tenerife, Canary Islands, Spain) used multiwalled carbon nanotubes as a solid-phase extraction (SPE) medium for extracting eight organophosphorus pesticides from various commercial apple, grape, orange, and pineapple juices. The pesticides were ethoprophos, diazinon, chlorpyriphos-methyl, fenitrothion, malathion, chlorpyriphos, fenamiphos, and buprofezin. In this method, the SPE step was followed by gas chromatography with nitrogen–phosphorus detection.
