Abstract

Synthesis and characterization of potassium zinc hexacyanoferrate (KZnFC) as nano ion exchanger material are performed. Sorption characterization investigations on the removal of some radionuclides (134Cs, 60Co), heavy metal (Pb2+) and lanthanides (Ce3+ and Gd3+) from aqueous and nitric acid solutions using mesoporous KZnFC ion exchange have been done. Selective removal of 134Cs rather than 60Co and Ce3+ (lanthanides) is achieved in aqueous solution and nitric acid solution, respectively. The maximum sorption capacity of 134Cs, 60Co, Pb2+, Ce3+ and Gd3+ is 170, 10.5, 3.88, 0.72 and 0.55 mg/g, respectively, onto nano-material of KZnFC.
