1. A method for preparing an adsorbent from sugarcane bagasse and a polyolefin, the method comprising:

obtaining sugarcane bagasse;

pyrolyzing the sugarcane bagasse to provide a sugarcane bagasse char;

activating the sugarcane bagasse char to provide an activated sugarcane bagasse char;

dissolving a polyolefin in an organic solvent to obtain a polyolefin solution;

dispersing the activated sugarcane bagasse char in the polyolefin solution to provide a mixture;

extracting the organic solvent from the mixture to provide a composite;

annealing the composite to provide the adsorbent; and

cutting the adsorbent to provide adsorbent flakes,

wherein the adsorbent flakes have sizes ranging from about 3 mm to about 30 mm.
