INVESTIGATION OF URANIUM ADSORPTION ON ACTIVATED CARBON

Öz

Activated carbon is widely used in the field of nuclean technology because of some specific properties, such as stability towards high temperature and high dose of radiation. The adsorption of aranium on commercially available activated carbon (Merck 2183) has been studied as a function of shaking time, pH, concentration of adsorbate and temperature. The uranium adsorption efficiency was found as 97 ± 1 %.

AKTİF KARBON ÜZERİNE URANYUM ADSORBSİYONUNUN İNCELENMESİ

Öz

Aktif karbonun, yüksek sıcaklığa ve yüksek radyasyon dozuna karşı kararlılığı nedeniyle nükieer teknoloji alanında geniş bir kullanım alanı vardır. Ticari aktif karbon (Merck 2183) üzerine uranyum adsorpsiyonu çalkalama süresi, pH, başlangıç uranyum konsantrasyonu ve sıcaklığın bir fonsiyonu olarak incelenmiştir. Uranyum adsorpsiyon verimi %97±1 olarak bulunmuştur.
