Abstract (2. Language): 
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

Abstract (Original Language): 
Endüstriyel faaliyetler neticesinde, yüzey sularının ağır metal kirliliği artmıştır. Özellikle biyolojik arıtım sürecinde ağır metaller, mikroorganizmalara öldürücü etki göstermektedir. Ayrıca gerek tarımsal amaçlı kullanılan sularla sulanan bitkilerde, gerekse sucul canlılarda biriken ağır metaller, onları kullanan insanlarda da birikime sebep olmaktadır. Bu sebeple hem biyolojik arıtma yapılacak atık su, hemde alıcı ortama bırakılacak atık suların ağır metallerden arındırılması önem kazanmaktadır. Bu çalışmada sulardaki kadmiyum kirliliğinin dolgulu kolonlarda adsorpsiyon yoluyla giderilmesi araştırıldı. Adsorbent olarak; at kestanesi ve meşe palamudu kullanıldı.Yapılan çalışma sonucunda meşe palamudunun 26,32 mg kadmiyum/g adsorbent, at kestanesi ise 14,59 mg kadmiyum/g adsorbent adsorplama kapasitelerine sahip olduğu belirlenmiştir. Ayrıca en yüksek adsorplama kapasitesi, meşe palamudu kadehinde 40,24 mg kadmiyum/g adsorbent olarak tespit edilmiştir.
