Adsorption of Quinoline from Aqueous Solution by NaOH-treated Biochar derived from Orange Peel: Response Surface Methodology Optimization

Abstract

During this research project, response surface methodology (RSM) was used to optimise the adsorption of quinoline on modified orange peel biochar (MOPBC). The RSM was laid out using a design of experiments CCD (central composite design) with three experimental factors: initial concentration, temperature, and adsorbent dosage as the main variables. The F-value of the model was 97.16 with a p-value less than 0.0001. Indicated that the experimental data does not deviate from the model. The maximum quinoline removal of 98.01% when initial concentration dsorbent dosage and temperature were 50 mg/L, 0.02g and 40 °C.
