The Modeling of Radioactive Cobalt Adsorption on Molecular Sieves
Abstract
Radioactive wastes are products of nuclear activities around the world. Radioactive cobalt is one of the usually found radionuclide in nuclear waste. It is crucial to separate radioactive cobalt from aqueous media. The removal of radioactive cobalt (Cobalt-60) was investigated using molecular sieves in this study. The molecular sieves structure comprises of a microporous and aluminosilicate framework. Due to their chemical composition and structures molecular sieves have excellent sorption capacities. The response surface methodology was utilized to constitute the predictive regression model. The experimental minimum and maximum decontamination factor 2.5 and 11.1 was obtained, respectively. The predicted maximum decontamination factor was 10. Molecular sieves present a high adsorbent capacity for the disposal radioactive cobalt from water solution.
