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).

Abstract-The influence of the ultrasonication conditions (time and amplitude of ultrasonication) upon the adsorptive properties of the obtained ionic liquid impregnated material, in the removal process of Cs + ions from aqueous solutions, was studied. In the last years ionic liquids was used for the treatment of waste waters containing radionuclides. In order to minimize the treatment cost and to enhance the treatment efficiency, as an alternative to liquid-liquid extraction processes, the use of ionic liquid impregnated support was proposed as a new concept. In the present paper the ultrasonication was used for the impregnation of 1-Butyl-3-methylimidazolium hexafluorophosphate-[BmimPF6] onto Florisil support. Different physical-chemical analysis (scanning electron microscopy (SEM), energy dispersive XRay analysis (EDX), and FTIR-Fourier transform infrared spectroscopy) was used to characterize the obtained ionic liquid impregnated material. In order to obtain a stable and homogenous impregnation of the solid support surface with the studied ionic liquid which will achieve reproducible results in the Cs + adsorption processes it is not necessary to increase the ultrasonication time, but it should be used higher amplitude. The adsorption performance of the Florisil impregnated with [BmimPF 6 ], using optimum conditions of ultrasonication, was studied as a function of Cs + ions initial concentrations. Adsorption isotherms like Langmuir, Freundlich, Dubinin-Radushkevich (D-R), and Temkin were used to analyze the equilibrium data at different concentrations. The experimental data showed good fit to the Langmuir isotherm, followed by the Temkin and Dubinin-Radushkevich isotherms and then the least fit was obtained with the Freundlich isotherm.

“…This suggests the CuHCF NPs film can be successfully regenerated by a reversible oxidation reaction from CN-Fe(II) to CN-Fe(III). In contrast to the conventional method using powder or bulk MHCF sorbents [8,12,13], the effective regeneration performance suggested the battery column system can be utilized in a close circuit.…”

“…Previous studies have focused on MHCFs associated support materials (such as polyacrylonitrile, [12] carboxylic latex [13] and mesoporous silica [14]) with suitable size and shape properties for Cs removal in columns. On the other hand, combined sorbents have been found to possess substantial disadvantages when faced with an enormous challenge of regeneration.…”

As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. Insignificant change in the current after 100 cycles of durability test indicated the CuHCF NPs film is relatively stable, suggesting the battery-type column has a long service life for Cs removal from wastewater.
