Abstract
We tried to develope pretreatment method for pesticides in golf course with use of solid phase extraction. Recovery rates of 24 pesticides, analyzable with GC/MS, with using of various solid phase extraction as a pretreatment were investigated. Reverse type solid phase, silica-based and ODS bonded, showed better recovery rates with the exception of trichlorfon. Trichlorfon could be well extracted when NaCI was added and solid phase extraction was successively used. As for polystyrene gel and polymethacrylate gel as solid phase, good recovery rates were obtained with a careful selection of solvents as elute with the exception of some pesticides.
As for 7 pesticides, analyzable with HPLC, good recovery rates were obtained with using of poly-styrene gel and polymethacrylate gel as a solid phase.
These sollid phase extraction method was applied to actual environmental samples.
