Abstract
A method of preparing an adsorbent can include pyrolyzing sugarcane bagasse to provide a bagasse char, activating the bagasse char, dissolving polyolefin waste in an organic solvent to obtain a solution, dispersing the bagasse char in the solution to provide a mixture, extracting the organic solvent from the mixture to provide a composite, and annealing the composite to provide the adsorbent. The adsorbent can be porous.
Claims16
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.
