Özet

By development of industrial activities, there has been an increase of heavy metal pollution in surface waters. During biological purify cation processes, the heavy metals have high toxic effects, especially on the microorganisms. Apparently, the heavy metals accumulating within plants watered using agriculture waters, and within the aquatic living things cause an accumulation in human beings. Because of this reason, the treatment of heavy metals from wastewaters that will be used in biological treatment as well as the purifications of water releasing to the environment gains importance. In this study, the removal of cadmium pollution using packed adsorption columns has been investigated. Oak valonia and horse chestnut have been used as adsorbents. At the result of the study, adsorption capacities of oak valonia and horse chestnut were determined as 26.32 and 14.59 mg cadmium /g adsorbent respectively. Also, there is maximum adsorption capacity in pedincula of oak valonia and this value is 40.24 mg cadmium/g adsorbent.
