Abstract
This research studies batch adsorption in laboratory scale for the removal of humic acid by chitosan-silica resin as an adsorbent. It was found that adsorption capacity of 0.2 g of chitosan silica resin with varying initial humic acid concentration of 13.5, 17.5 and 22.5 mg/L were 0.86, 0.92 and 1.15 mg/g, respectively. The equilibrium of adsorption was studied by Langmuir and Freundlich equations. It was found that the equilibrium of adsorption followed by Freundlich equation. Batch design to achieve 100% of humic acid removal for 1 L was 91.3 g.
