Color removal via adsorption on wood shaving

Factors affecting the adsorption capacity of dyes on wood shavings, such as the mesh size of the adsorbent, wood dosages, contact time, and the structure of the adsorbant, were studied. Adsorption of dye on wood follows the classical Freundlich's isotherm. Available results indicated that wood shaving is a good adsorbent. Its capacity varies according to the structure of the dye and mesh size. Powdered activated carbon was used as a reference adsorbent for the same dyes under investigation.
