Disclosed is a method for removing an ionic species contained in an aqueous phase. The method includes contacting an aqueous phase containing the ionic species with a sol-gel composite material, where the sol-gel composite material is a sol-gel composition having a porous matrix and containing a reactive metal incorporated into at least a portion of the porous matrix, under conditions sufficient to remove the ionic species contained in the aqueous phase.

Disclosed is a method for removing an ionic species contained in an aqueous phase. The method includes contacting an aqueous phase containing the ionic species with a sol gel-derived composite material, where the sol gel-derived composite material is a sol gel-derived composition having a porous matrix and containing a reactive metal incorporated into at least a portion of the porous matrix, under conditions sufficient to remove the ionic species contained in the aqueous phase.

An anaerobic to aerobic sequence enhances biological degradation of many organic pollutants. Exemplary embodiments provide systems and methods for effective treatment of storm-water runoff pollutants such as hydrocarbons, nitrates, phosphorus, and heavy metals using sediment filtration and adsorption, and biochemical processes under bi-phasic bioretention conditions. By integrating these pollution cleanup pro-usages into a single unit, this apparatus optimizes retention time of the runoff through the system and maximizes removal rates of runoff pollutants, resulting in more reliable and efficient treatment mechanism than previous systems.
