Bu çalışmada, hem ekonomik hem de doğal olarak temin edilen doğal Kula volkanit adsorbanı üzerine sulu çözeltilerden U(VI) metal iyonlarının adsorplanma kabiliyeti karakterize edilmiştir. U(VI) iyonlarının doğal Kula volkanit üzerine adsorpsiyonunu etkileyen parametrelerden pH, adsorban madde miktarı, uranyum iyonlarının konsantrasyonu, sıcaklık ve temas sürenin etkisi incelenmiştir. U(VI) iyonunun doğal Kula volkanit üzerine adsorpsiyonunun deneysel sonuçları Langmuir, Freundlich ve D-R izoterm modellerine uygulanarak, değerlendirilmiş ve elde edilen verilere göre U(VI) iyonunun adsorpsiyonu en iyi Langmuir ve D-R izotermlerine uygunluk göstermiştir. Çalışmada beş farklı (298.15, 303.15, 308.15, 313.15, 318.15 K) sıcaklıkta bir dizi deneyler yapılarak, uranyum iyonu için ∆Go, ∆Ho ve ∆So gibi termodinamik parametreleri hesaplanmış ve adsorpsiyonun kendiliğinden ve endotermik olduğu tespit edilmiştir. Bu çalışmadan elde edilen sonuçlara göre sulu çözeltilerden U(VI) iyonlarının gideriminde doğal Kula volkanitin adsorplama kabiliyetinin oldukça yüksek olduğu söylenebilir.

Adsorption of Uranium(VI) Ions on the Kula Volcanite

Öz

In this study, the ability to adsorb U(VI) metal ions from aqueous solutions on the natural Kula volcanic adsorbent, which is both economically and naturally supplied, was characterized. The effects of pH, amount of adsorbent material, concentration of uranium ions, temperature, and contact time, which are among the parameters affecting the adsorption of U(VI) ions on the natural Kula volcanite, were investigated. According to the experimental results of the adsorption of U(VI) ions on natural Kula volcanite, Langmuir, Freundlich, and D-R isotherm models were evaluated, and according to the obtained data, the adsorption of U(VI) ions showed the best compatibility with Langmuir and D-R isotherms. In the study, a series of experiments were carried out at five different (298.15, 303.15, 308.15, 313.15, 318.15 K) temperatures, and thermodynamic parameters, such as ∆Go, ∆Ho, and ∆So for the uranium ion were calculated, and it was determined that the adsorption was spontaneous and endothermic. According to the results obtained from this study, it can be said that the adsorption ability of natural Kula volcanite in removing U(VI) ions from aqueous solutions is quite high.
