Abstract
Disclosed are processes to treat water having halide ions and organohalides. The process comprises contacting a plant biomass with an alkaline solution to give an alkaline plant biomass, and contacting the alkaline plant biomass with water to give a biomass material. An aqueous sample with organohalides or halide ions is contacted with the biomass material to provide a low halide filtrate and a spent biomass.
Claims16
A method for removing a halide, a herbicide, or a combination thereof in an aqueous sample, the method comprising:
- contacting a plant biomass with an alkali solution to give an alkaline plant biomass;
- trans-esterifying the alkaline plant biomass to obtain a treated plant biomass;
- and
- contacting the treated plant biomass with the aqueous sample to remove the halide, the herbicide, or a combination thereof from the aqueous sample.
A bio filter comprising a trans-esterified plant biomass having an average particle size of about 1 micron to about 5000 microns.
