Removal of Reactive Blue (RB2) from Aqueous Solution by Chitosan/Diatomite Biocomposite

Abstract:

The adsorption behavior of Reactive Blue (RB2) dye from aqueous solution on chitosan/diatomite biocomposite adsorbent was studied. The effects of biocomposite adsorbent ratio and pH on removal of RB2 were examined, and optimum experimental conditions were identified. Biocomposite adsorbent had the largest adsorption efficiency when the ratio was 10 wt%. The maximum percentage removal of RB2 was 96.36% which obtained at pH 4.0. Adsorption equilibrium showed adsorption amount of RB2 improved with increase in the amount of NaCl, indicating that the addition of inorganic salt was an advantage of the removal of RB2.
