Abstract
A method of removing at least one cationic dye from an aqueous solution. The method includes contacting the aqueous solution with an adsorbent comprising a water-insoluble membrane disposed on a substrate. The water-insoluble membrane comprises cross-linked humic acid, at least one alginate, and hydroxyethyl cellulose. The contacting forms a treated aqueous solution having a lower concentration of the at least one cationic dye relative to the aqueous solution.
