This study investigates the properties and potential application of Mg-PKS biochar composite for methylene blue solution (MB) adsorption. The Mg-PKS biochar composite was developed from palm kernel shell biochar via steam activation followed by MgSO4 treatment and carbonization. The effect of process parameters such as solution pH (4-10) contact time (30-90 min) and adsorbent dosage (0.1-0.5 g) were investigated via central composite design response surface methodology. Results revealed that the Mg-PKS biochar composite has irregular shapes pore structure from SEM analysis a surface area of 674 m2g-1 and average pore diameters of 7.2195 m based on BET analysis. RSM results showed that the optimum adsorption of MB onto Mg-biochar composite was at pH 10 30 min contact time and 0.5 g/100 mL dosage with a removal efficiency of 98.50. In conclusion Mg treatment is a potential alternative to other expensive chemical treatment methods for biochar upgrading to the adsorbent.

Abstract

This study investigates the properties and potential application of Mg-PKS biochar composite for methylene blue solution (MB) adsorption. The Mg-PKS biochar composite was developed from palm kernel shell biochar via steam activation followed by MgSO4 treatment and carbonization. The effect of process parameters such as solution pH (4-10) contact time (30-90 min) and adsorbent dosage (0.1-0.5 g) were investigated via central composite design response surface methodology. Results revealed that the Mg-PKS biochar composite has irregular shapes pore structure from SEM analysis a surface area of 674 m2g-1 and average pore diameters of 7.2195 m based on BET analysis. RSM results showed that the optimum adsorption of MB onto Mg-biochar composite was at pH 10 30 min contact time and 0.5 g/100 mL dosage with a removal efficiency of 98.50. In conclusion Mg treatment is a potential alternative to other expensive chemical treatment methods for biochar upgrading to the adsorbent.
