The adsorption kinetic models suggest the adsorption process is complex, involving more than one mechanism. The mechanism may involve adsorption of dye at an active site on the surface, diffusion and adsorption into the interior pores of the AC…

The used of easy ignited cocoa shell pellet as fire starter that convenient and safe to use and stored for long periods without losing its efficiency.

The mechanism may involve adsorption of dye at an active site on the surface, diffusion and adsorption into the interior pores of the AC particle. The results of this study show that the activated carbons derived from cocoa shell can be used as…
