Radyoaktif kobalt, radyoaktif atıkta en bol bulunan radyonüklidlerden biridir. Bu çalışmada, radyoaktif kobaltın (60Co) su çözeltisinden zeolit 3A ve 5A ile adsorpsiyon yoluyla uzaklaştırılması araştırılmıştır. Cevap yüzey yöntemi, radyoaktif kobaltın uzaklaştırılmasında dekontaminasyon faktörünü tahmin etmek için öngörücü regresyon modelini oluşturmada kullanılmıştır. Deneysel maksimum dekontaminasyon faktörü zeolit 3A ve zeolit 5A için sırasıyla 30.37 ve 15.9 olarak elde edilmiştir. Hesaplanan model zeolit 3A ve 5A için anlamlıydı (p <0.05). Zeolit 3A ve zeolit 5A için tahmin edilen maksimum dekontaminasyon faktörü, optimum koşullarda sırasıyla 30.05 ve 15.19'dur. Sulu çözeltiden radyoaktif kobaltın uzaklaştırılmasında zeolit 3A, zeolit 5A'dan daha yüksek adsorban kapasitesine sahiptir.

Zeolite Used for Optimized Removal of Radioactive Cobalt with Response Surface Methodology

Öz

Radioactive cobalt is one of the most abundant radionuclides in radioactive waste. This study investigated the removal of radioactive cobalt (60Co) by adsorption with zeolite 3A and 5A from aqua solution. The response surface methodology was employed to constitute the predictive regression model to guess the decontamination factor for radioactive cobalt removal. The experimental maximum decontamination factor 30.37 and 15.9 were obtained for zeolite 3A and zeolite 5A, respectively. The calculated model was significant for both zeolite 3A and 5A (p<0.05). The predicted maximum decontamination factor was 30.05 and 15.19 in optimum conditions for zeolite 3A and zeolite 5A, respectively. Zeolite 3A has a higher adsorbent capacity than zeolite 5A for the removal of radioactive cobalt from aqueous solution.
