Adsorption of sulfur dioxide (SO2) gas using treated rice husk ash (RHA) adsorbent / Nurul Najwa Abd Malek and Rusdin Laiman

The aim of this study was to investigate the potential of treated rice husk ash (RHA) as adsorbent to adsorb acidic SO2 gas. The treated RHA was prepared using a water hydration method by mixing the RHA, Calcium oxide (CaO) and Sodium Hydroxide (NaOH). The addition of NaOH is to increase the dissolu...
