Preparation of Activated Charcoal with High Surface Area from an Agriculture Wastes and Industrial Residues

Abstract

This work was concentrated on preparation of activated carbon which also call (charcoal) from natural agricultural wastes (leg & leaves and empty ear of corn, Wheat & Barley grass and herb residues) and industrial residues (Paper drafts and Sawdust). These residues were treated first with Sodium Hydroxide (1:2) (1 of the raw materials : 2 of NaOH), then burning at 550 ± 25 °C for three hours to complete the carbonization process. The reaction mixture was purified by washing with distillation water and neutralized using 10% Hydrochloric acid. Reflux for one hour, filtrate and washing with distilled water, and leaves to dry at 110 – 120 °C for 24 hours. The physical properties of preparing activated carbon were determined and compared with a commercial activated carbon which supply by B.D.H. chemical company
