A method of preparing an adsorbent can include pyrolyzing date pit to provide a date pit char, activating the date pit char, dissolving polyolefin waste in an organic solvent to obtain a solution, dispersing the date pit char in the solution to provide a mixture, extracting the solvent from the mixture to provide a composite, and annealing the composite to provide the adsorbent. The adsorbent can be porous.
