Abstract
The present disclosure relates to water purification compositions and the method of producing the same. Specifically, the present disclosure relates to compositions containing a substrate that has hydroxyl, thiol, carboxyl or amino groups, a metal oxide, and a carboxylic acid compound, and the method of producing the same. The composition is useful for the removal of soluble phosphorus, selenium, fluoride, arsenic and other heavy metal contaminants that may be present in water. The composition could be of use in numerous fields, including but not limited to, oil and gas, mining, storm water, agricultural runoffs, municipal wastewater, and industrial wastewater.
Claims29
A water purification composition comprising a substrate with a surface containing hydroxyl, thiol, carboxyl and/or amino groups, a carboxylic acid compound, and a metal, wherein the metal cross-links the hydroxyl, thiol, carboxyl and/or amino groups on the surface of the substrate, and the carboxylic acid compound.
