Abstract
A method for providing superadsorption of polar organic compounds using a material system comprising the steps of 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 method for providing superadsorption of polar organic compounds using a material system comprising the steps of:
- (a) 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
- (b) employing consequence management by maintaining a high rate of adsorptivity combined with high fidelity and accuracy of the material system.
A method for modifying a superadsorbent material for air sampling applications comprising:
- submerging a superadsorbent material in a Schlenk flask, wherein the Schlenk flask contains a charged bath;
- degassing the Schlenk flask;
- heating the charged bath to a temperature;
- removing the superadsorbent material from the charged bath;
- washing the superadsorbent material;
- and
- drying the superadsorbent material.
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.
