The present paper investigates the application of coconut stalk fibre to remove phenol from wastewater in a packed column. The influence of operating conditions like flow rate (5, 10, 15 mL/min) and bed height (4, 8 and 12 cm) on the adsorption were investigated. The dynamic behavior of the packed column was studied by drawing the breakthrough curves. The experimental data were investigated by using Thomas model and BDST model. It was found that the adsorption capacity increased with increase in flow rate and bed depth. The BDST model was employed to calculate the service time required for saturation of the bed which will be used for the design of the column. The adsorption capacity was evaluated as 215.5 mg/g showing that coconut stalk is a promising adsorbent.
