Biosorption of Ni(II) using alkaline-treated rice husk / Insyirah Mohamad Shah

Rice husk has been widely reported as a good sorbent for heavy metals. Alkaline-treated rice husk were used to investigate the potential of Ni(II) adsorption from synthetic solutions and wastewater in batch systems. Effects of operational variables such as pH, contact time, adsorbent dose, initial N...
