MODIFIED LIQUID ACTIVATED CARBON (FE-LAC) FOR IN-SITU ARSENIC REMOVAL
This abstract first appeared for US patent application 18348045 titled 'MODIFIED LIQUID ACTIVATED CARBON (FE-LAC) FOR IN-SITU ARSENIC REMOVAL
Original Abstract Submitted
A composition for groundwater remediation includes an iron-modified liquid activated carbon which includes a plurality of particles of liquid activated carbon, iron disposed on each surface of the plurality of particles of liquid activated carbon, and an aqueous fluid. A method to produce a composition for groundwater remediation includes producing a liquid activated carbon, and modifying the liquid activated carbon with iron to produce an iron-modified liquid activated carbon. A method for in-situ groundwater remediation includes utilizing a series of chemical injectors to inject an optional first zone with a commercial oxidant and utilizing a series of chemical injections to inject a second zone reactive barrier with an iron-modified liquid activated carbon.
