Removal of malathion using selected granular activated carbons

Abstract

The usage of malathion pesticide and a subsequent release into the environment was a major concern worldwide due to detrimental effect and their toxicity to ecosystem. Some studies showed that granular activated carbon (GAC)becomes the most effective adsorbents for the removal of pesticides. Therefore, a study was carried out to investigate the potential and effectiveness of four different types of granular activated carbon (GAC) namely coal base, coconut shell, palm shell and peat base to remove pesticides particularly malathion.
