Different generations of modified silica gel with polyamidoamine (PAMAM) dendrimers were synthesized.The adsorbents characterized using Fourier transform infrared, scanning electron microscopy energy dispersive X-ray spectroscopy thermal gravimetric analysis and porous structure analysis.The uptake behavior Si-6G PAMAM toward U(VI) at different experimental conditions pH, time, temperature concentration was studied batch mode.The maximum adsorption capacity 303.03 mg g -1 as described...
Abstract PAMAM dendrimers modified silica gel terminated phenylphosphonic acid-amide moieties (Si-6G PAMAM-PPAAM) was prepared for uranium(VI) adsorption from aqueous solutions by batch and fixed-bed column methods. The experimental results showed that the maximum capacity 434.78 mg g −1 . Equilibrium isotherm data obeyed Langmuir model. Kinetic followed pseudo-second order model thermodynamic parameters implied spontaneous, endothermic. performance of new adsorbent toward uranium using...
The environment is at risk from radioactive waste containing uranium ions.A nano-sized copper potassium hexacyanoferrate encapsulated O-carboxymethylchitosan (CuHCF/O-CMCs) matrix was used to extract U(VI) ions the manufactured wastewater in this investigation.The synthesized CuHCF/O-CMCs nanocomposite prepared by methylation of chitosan form (O-CMCs).The nanoparticles (CuHCF) were dispersed aqueous solution O-CMCs presence calcium chloride give a nanocomposite.Fourier-transform infrared...
