Adsorption of Cyanide from Cassava Wastewater Using Calcined and Activated Oyster Shell Ash

Oto-Obong P. Akpan & B. R. Etuk · Journal of Engineering Research and Reports · 2019

Calcined ash and activated ash adsorbents were prepared from oyster shell. The physico-chemical properties of the prepared calcined oyster shell ash (COSA) and activated oyster shell ash (AOSA) were obtained using ASTM standards and Sears method. The results show that AOSA is a b...
