Simultaneous Removal of Chromotrope 2B and Radionuclides From Mixed Radioactive Process Wastewater Using Organo-Bentonite

Abstract

KEYWORDSThe simultaneous removal of cationic radionuclides, 137 Cs(I), 60 Co(II) and 152+154 Eu(III), and a chemically toxic anionic pollutant, the analytical reagent chromotrope 2B (C2B), from simulated mixed radioactive process wastewater (MRPWW) has been investigated using bentonite modified with cetyltrimethylammonium bromide. Modification was confirmed by elemental analysis, X-ray diffraction and infrared spectroscopy. Bentonite partially modified to 78% of the cation exchange capacity (PMB) was found ca…
