Claim 0:
1. A method for preparing an adsorbent from olive stone and a polymer, comprising:
obtaining olive stones;
cutting and drying the olive stones to obtain dried olive stone pieces;
alkali-activating the dried olive stone pieces to obtain alkali-activated olive stone pieces;
pyrolyzing the alkali-activated olive stone pieces to obtain alkali-activated olive stone char;
acid-activating the alkali-activated olive stone char to obtain acid-activated olive stone char;
dissolving at least one polymer in an organic solvent to obtain a polymer solution;
dispersing the acid-activated olive stone char in the polymer solution to obtain a mixture;
extracting the organic solvent from the mixture to obtain a composite; and
annealing the composite to provide the adsorbent.
