Sorptive Removal of Radionuclides (Cobalt, Strontium and Cesium) using AMP/IO-PAN Composites

Abstract

Applicability of ammonium molybdophosphate/iron oxides-polyacrylonitrile (AMP/IO-PAN) composites on the removal of radionuclides in the radioactive wastewater generated from nuclear power plants was investigated. The composites were characterized using the following analytical techniques: X-ray diffraction (XRD), Fourior transform-infrared (FT-IR) spectroscopy, scanning electron microscopy (SEM), particle size analyzer (PSA), nitrogen adsorption-desorption and magnetic property measurement system (MPMS).

Selective strontium adsorption using synthesized sodium titanate in aqueous solution

“…13 Several types of organic and inorganic adsorbents such as natural zeolites, porous carbon composites, graphene oxides, ammonium molybdophosphate composites, hydroxyapatites, and sodium titanates have been used for removing strontium from aquatic circumstances. 10,14–18 In particular, sodium titanates have distinctive physico-chemical characteristics such as a low temperature compound, chemical stability at high pH, and great ability to adsorb strontium, uranium, neptunium, and plutonium in a wide range of pH and high salt concentrations. 19–22 Several sodium titanate composites such as monosodium titanates, sodium peroxotitanates, sodium nonatitanates, and sodium iron titanates have been developed for effective adsorption of strontium in aquatic environment that includes diverse radionuclides.…”
