Abstract
A method for providing superadsorption of polar organic compounds using a material system is provided. The method can comprise enhancing adsorption by means of using high surface area and mass transfer rates and decreased reactivity at surface sites attractive to the polar compounds; and employing consequence management by maintaining a high rate of adsorptivity combined with high fidelity and accuracy of the material system. A modified superadsorbent material for air sampling applications comprising a superadsorbent material treated with a solution, thereby forming a treated superadsorbent material, wherein the treated superadsorbent material is substantially hydrophobic and is capable of adsorbing polar compounds.
