Abstract
Bu çalışmada, kobalt ve nikelin bentonit üzerine adsorpsiyonu ve bulunduğu matriksten desorpsiyonu amaçlanmıştır. Ayrıca, kolon akış hızının ve kolonda kalma süresinin etkileri incelenmiştir. Maksimum verim için optimum şartlar tespit edilmiştir. Bentonit, organik ve inorganik iyonları iyi adsorplaması, ucuz ve her yerde bulunması nedeniyle çalışmamızda kullanılmıştır. Denge verileri Langmuir ve Freundlich izotermleri kullanılarak çizilmiştir. Herbir izoterm için karakteristik parametreler tespit edilmiştir. Langmuir ve Freundlich modelleri deneysel verilerle iyi bir uyum sağlamıştır.

Abstract
This study aims at the adsorption of cobalt, nickel on bentonite and the desorption from their matrix. Also column flow speed, remaining time in the column effects were investigated. For maximum yield optimum conditions was determined. Bentonite was used in our study due to adsorptive affinity for organic and inorganic ions, cheap and everywhere to be found. The equilibrium data was analysed using the Langmuir and Freundlich isotherms. The characteristics parameters for each isotherm were determined. The Langmuir and Freundlich models agree very well with experimental data.
