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

摘要

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