Optimization of operating parameters on the activated carbon from Pinang frond for adsorption of remazol brilliant blue R

Abstract

Activated carbons are frequently utilized for waste water treatment especially in dye removal in textile industries. With high level of carbon content, various organic materials have been chosen as based materials for activated carbon. In this study, activated carbon from pinang frond (PFAC) was created by using a physical activation and optimized the operating parameters such as activation temperature (°C), activation time (hour) and, CO2 flow rate (mL/min). Experimental design (DoE) for PFAC preparation was developed and optimized using response surface methodology (RSM). It was found that the optimum PFAC preparation conditions was at the activation temperature of 867°C, activation time of 6.0 hour and CO2 flow rate of 476 mL/min. By verification with experimental values, the predicted values from the model was only less than 2% of errors for RBBR removal onto PFAC. This can be pointed out that the model is sufficient and suitable to predict the operating parameters fixed responses.
