described is a method for producing copolymerized sol - gel derived sorbent particles for the production of copolymerized sol - gel derived sorbent material . the method for producing copolymerized sol - gel derived sorbent particles comprises adding a basic solution to an aqueous metal alkoxide mixture for a ph ≦ 8 to hydrolyze the metal alkoxides . then , allowing the mixture to react at room temperature for a precalculated period of time for the mixture to undergo an increased in viscosity to obtain a desired pore size and surface area . the copolymerized mixture is then added to an immiscible , nonpolar solvent that has been heated to a sufficient temperature wherein the copolymerized mixture forms a solid upon the addition . the solid is recovered from the mixture , and is ready for use in an active sampling trap or activated for use in a passive sampling trap .
