Dyes Adsorption On Salak Peel Based Activated Carbon Optimization, Equilibrium, Kinetic And Thermodynamic Studies

The adsorption of malachite green (MG) and remazol brilliant blue R (RBBR) dyes onto salak peel activated carbon (SPAC) were investigated in a batch process. Salak peel undergoes physiochemical activation process which involves potassium hydroxide (KOH) impregnation and carbon dioxide (CO2) gasifica...
