Investigations on sorption performance of some radionuclides, heavy metals and lanthanides using mesoporous adsorbent material

Synthesis and characterization of potassium zinc hexacyanoferrate (KZnFC) as nano ion exchanger material are performed. Sorption characterization investigations on the removal of some radionuclides ( 134 Cs, 60 Co), heavy metal (Pb 2+ ) and lanthanides (Ce 3+ and Gd 3+ ) from aqueous and nitric acid solutions using mesoporous KZnFC ion exchange have been done. Selective removal of 134 Cs rather than 60 Co and Ce 3+ (lanthanides) is achieved in aqueous solution and nitric acid solution, respectively. The maximum sorption capacity of 134 Cs, 60 Co, Pb 2+ , Ce 3+ and Gd 3+ is 170, 10.5, 3.88, 0.72 and 0.55 mg/g, respectively, onto nano-material of KZnFC.
