Abstract
Official abstract text for this publication.
Provided is a method of regenerating an acrylic resin (B2), comprising (A) providing a collection of particles of acrylic resin (B2) that has calculated Hansch parameter of −1.0 to 2.5, wherein one or more humic acid, one or more fulvic acid, or a mixture thereof, is adsorbed onto said acrylic resin (B2), and (B) bringing said collection of particles of acrylic resin (B2) into contact with an aqueous solution (RA) having pH of 4 or lower, to form a mixture B2RA, (C) then separating acrylic resin (B3) from said mixture B2RA.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of regenerating an acrylic resin (B2), comprising (A) providing a collection of particles of acrylic resin (B2) that has calculated Hansch parameter of −0.2 to 0.5, wherein one or more humic acid, one or more fulvic acid, or a mixture thereof, is adsorbed onto said acrylic resin (B2), and (B) bringing said collection of particles of acrylic resin (B2) into contact with an aqueous solution (RA) having pH of 4 or lower, to form a mixture B2RA, (C) then separating acrylic resin (B3) from said mixture B2RA. 2. The method of claim 1 , wherein said aqueous solution (RA) has pH of 1 or lower.
