Application of Carbonized Poultry Waste in the Removal of Chemical Oxygen Demand (COD) from Dye Wastewater: Kinetic Study

The removal of COD from dye wastewater by poultry waste activated carbon using KOH as an activating agent was carried out with two step process. Batch adsorption method was employed at various contact time. The study indicated optimum COD removal of 65.15% at the contact of 120 minutes and 150 minutes respectively. In the kinetic study, pseudo first-order, pseudo second-order, Natarajam and Khalaf first order and elovich model were tested but pseudo second-order showed the best fit for the adsorption process. The result further revealed that poultry waste, an available adsorbent is very effective in COD removal from dye wastewater.
