Activated carbon from agricultural by-products for the removal of Rhodamine-B from aqueous solution.

Bagasse pith (BP) has been utilized for activated carbon preparation using H(3)PO(4) (BPH) or KOH (BPK) as a chemical activating agent followed by carbonization at 500 degrees C. The physicochemical properties of activated carbon were carried out. The effectiveness of carbon prepared in adsorption of Rhodamine B (RhB) has been studied as a function of adsorbent type, pH, particle size, agitation time, temperature, initial dye concentration, and desorption.
