Preparation of phosphoric acid activated carbons from Canarium Schweinfurthii Nutshell and its role in methylene blue adsorption

Activated carbons were prepared by phosphoric acid activation of Canarium Schweinfurthii spent nutshell. The activation conditions for particles with average diameter of 2.36 mm, conducted in nitrogen chamber, were evaluated at 40 and 60% acid concentration, substrate/activating agent  (impregnation) ratio of 1:1 to 1:4, activation time of 20 to 60 min and temperatures of 200 and 400°C. The results showed that...
