Abstract

ABSTRACT: Six biochars derived from olive mill solid waste were prepared by varying the temperature and treatment with FeCl3 . The adsorption capacity of the biochar increased with the pyrolysis temperature and was in the order pre-treated>post-treated>untreated. The Langmuir isotherm and the pseudo-second-order kinetic models best fit the experimental results. The 550°C pre-treated biochar had the highest adsorption capacity from aqueous solutions (103.9 and 73.9 mg.g −1 at pH = 2 and 5, respectively). Chemisorption was the dominating mechanism. The adsorption capacity using olive mill wastewater was 51.3 mg.g −1 . This work demonstrates that waste can be reused within the process to achieve cleaner production.
