Abstract
A composition for treating water including an organic soil amendment and having ions bound thereto is beneficial to aid in the removal of aqueous contaminants, such as phosphate, other phosphorus containing compounds, arsenic, arsenic containing compounds, fluorides, and PFAS from water. In these compositions the ions include rare earth cations, iron cations, and mixtures thereof. There are also methods for making these soil amendment compositions, as well as methods for using these compositions to effectively remove contaminants from water.
Claims13
A composition for treating water comprising (a) an organic soil amendment selected from the group consisting of superabsorbent polymers (SAPs), humic acid, humic acid salts, humic acid esters, and mixtures thereof and (b) rare earth cations, wherein the cations are bound to the soil amendment and wherein the composition comprises about 1% to about 50% by weight rare earth cations based on the total weight of the composition not taking into account any water present in the composition.
