Abstract
Different core shells nanocomposites CSNCs derived from copper hexacyanoferrate CHCF with copolymer of anthranilic acid with ortho aminophenol poly(AA-co-o-AP) and copolymer of anthranilic acid with ortho phenylenediamine poly(AA-co-o-PD) were synthesized by redox polymerization using ammonium peroxydisulfate (APS) as an oxidant.
The synthesis route included (i) synthesis of nanoparticles of CHCF (ii) plantation the nanocomposites core shell in polymer matrix of poly(AA-co-o-AP) and poly(AA-co-o-PD) during the copolymerization process.
The structures of the prepared CSNCs are confirmed via FT-IR, X-ray powder diffraction (XRD) and Thermogravimetric (TGA), TEM and SEM–EDX mapping. The SEM and TEM confirmed the nano structures of the prepared CHCF and CSNCs. Also, XRD analysis confirmed the expansion of the CHCF into poly(AA-co-o-AP) and poly(AA-co- o-PD). The surface area of CSNC was determined also by Brunauer-Emmett-Teller (BET).
The synthesized CSNCs used for sorption of cesium ions from aqueous solutions by ion exchange process between the potassium ions in CSNCs replaced by cesium ions. FTIR analysis confirmed the presence of CN bonds in the CSNCs adsorbents implying the successful plantation of CHCF on the copolymers, which was further supported by EDX mapping. The sorption process of the synthesized CSNCs towards cesium ions and the factors affecting on the cesium sorption from aqueous solutions were reported at the difference in pH, metal ion concentration, shaking time and temperature for the two core shell nanocomposites. Four modeling include on Langmuir, Freundlich, Temkin and Dubinin-Radushkevich
(D-R) isotherms models were studied, which the data were well fitted with Langmuir model suggesting that the uptake of Cs+ was monolayer and homogeneous. Also, the adsorption kinetics results were fitted well to pseudo-second-order model. Thermodynamic parameters were calculated in the temperature range of 25-60 °C and the data revealed that Cs+ sorption was endothermic, spontaneous, and more favorable at higher temperature. Up to 92% desorption of Cs+ was completed with 2 M KCl for the synthesized core shell nanocomposites CSNCs derived from copper hexacyanoferrate CHCF with copolymer of anthranilic acid with o-aminophenol poly(AA-co-o-AP) and copolymer of anthranilic acid with o-phenylenediamine poly(AA-co-o-PD).
