Preliminary Study on the Porous Polymeric SPME Coating Prepared by in-situ Polymerication

A new method of preparing organic porous polymeric SPME coating by using a one-step in-situ polymerization technique was described. The characteristics of the coating and the concentration of monomer in preparing the coating were investigated and optimized. The porous coating showed high selectivity in the extracting and analyzing benzene, toluene, ethylbenzene and xylene (BTEXs) in aqueous sample.
