<p> The ability of corn husk to remove methylene blue from solution was investigated. Factors such as initial dye concentration, contact time, adsorbent dosage ,pH of solution and morphology of corn husk were studied. Results show that Langmuir isotherm can be successfully applied to the methylene blue – corn husk system and that corn husk is a suitable adsorbent for such a dye. Maximum adsorption capacity is 99 mg/g mass as derived from Langmuir isotherm. Sem analysis was carried out and the results were obtain</p>
