Arsenic(III) Removal from Contaminated Water using Silica Ceramic: A Batch Adsorption Study

Md. Salim , Yukihiro Munekage and Kyaw Min Naing

Abstract:
The silica ceramic (S-K) has been used as a potential low-cost adsorbent for the removal of As(III) from contaminated water in batch studies. Results showed that an adsorbent dose at 90 g L-1 could effectively remove 96% of As(III) from initial concentration of 0.5 mg L-1 within 3 h. It was also reveled that As(III) uptake increased with increasing contact time and As(III) concentration decreased with increasing adsorbent dosage. It was observed that As(III) removal is relatively dependent on pH and temperature variations. High adsorption of As(III) was found at pH 7.5 and at 25 °C. The adsorption equilibrium data followed both Langmuir and Freundlich isotherms. The Freundlich isotherm provided the best correlation for the adsorption of As(III) onto the silica ceramic. The maximum capacity of adsorption was found (qm) 1.1041 mg g-1 at different concentrations at 40 g L-1 fixed adsorption dosage. The results suggest that silica ceramic (S-K) is a potential adsorbent for removal As(III) ions effectively from contaminated water.
