The transfer of hydroxyl radicals (·OH) from the liquid phase to the soil is anticipated to enhance the efficient direct oxidation of total petroleum hydrocarbons (TPHs) in the soil. Based on the polar/non-polar interactions of polymers in aqueous solutions, polar chitosan was used to chelate Fe2 +,...
