MalakootianM. 2200692This study was conducted in order to present more information and evidence to authorities to make them capable of making better decisions. Survey was done in batch conditions on wastewater of Binalood paint industries using different amount of wood ash as adsorbent and in variable pH from acidic to alkaline and different contact times. Cadmium measurement in samples was done with atomic absorption equipment and test methods were adapted from standard methods for the examination of water and wastewater. This investigation showed that wood ash has high effectiveness in cadmium removal and this effectiveness raises with the increase of the amount of adsorbent substance to 100 g L-1 wastewater, where adsorption rate reaches 97-98% in acidic, neutral and alkaline pH. Data concerning adsorption isotherms indicates that, adsorption process follows Freundlich model. Concerning the results of this research and other investigations, the use of fly ash and wood ash is recommended as a low cost and available material to remove cadmium from municipal and industrial wastewater.]]>Abraham, L.,1982Eaton, A.D., L.C.
