Response Surface Methodology for Radioactive Strontium Adsorption on Molecular Sieves

Abstract

In the nuclear industry, the disposal of radioactive waste is a crucial issue. Strontium is one of the most dangerous radionuclides to human health. In this study, strontium 85 adsorption on molecular sieves was investigated. The factors affecting the adsorption on molecular sieves were examined. In order to increase adsorption, the sorbent (molecular sieves) was activated before contact with radioactive strontium. The response surface methodology was used to evolve the predictive regression model for adsorption of radioactive strontium on molecular sieves. The experimental and predicted maximum decontamination factor 14.23 and 12.93 was obtained, respectively. Molecular sieves were found to be useful for the removal of radioactive strontium from water solution.
