Abstract |
In this study, a stationary phase based on organic monolith particles has been developed for solid phase extraction (SPE). Firstly, a soft organic monolith was prepared by heating the mixture of methyl methacrylate (MMA), trimethylolpropane trimethacrylate (TPTM), polyethyleneglycol (PEG 100,000), azobisisobutyronitrile (AIBN) and n-butanol. The soft solid bulk monolith was smashed into particles. The organic monolith particles were washed, dried and the very fine particles and residual chemicals were removed using cellulose thimble filters installed in a soxhlet apparatus. The final product was packed in a 3 ml SPE cartridge and used for solid phase extraction of dliakyl phthalates. An aqueous sample solution of 10 mL was prepared by dissolving dibutyl phthalate, dicyclohexyl phthalate and dioctyl phthalate at a concentration of 5 ppm each, and passed through the cartridge. The captured analytes were recovered with acetone and ethylacetate as the releasing solvents. The recovery was about 90% for all analytes. |
