SAŽETAK / ABSTRACT:
Rhenium is considered a strategically important metal with expanding industrial applications, leading to growing interest in its efficient extraction from aqueous solutions. In this study, a macroporous magnetic amino-functionalized glycidyl methacrylate (GMA)-based nanocomposite was used for Re(VII) ion sorption from aqueous solutions. The sorption was studied under non-competitive conditions by varying contact time and temperature at unadjusted pH. It was shown that sorption capacity increased with the increase of contact time and temperature. The maximum Re(VII) sorption capacity of 57.1 mg/g was attained after 180 min at 343 K. Pseudo-first order (PFO), pseudo-second order (PSO), liquid film diffusivity (LFD), and intra-particle diffusion (IPD) kinetic models were used to study the sorption kinetics. It was noticed that Re(VII) sorption follows a PSO kinetic model. The sorption mechanism was intra- particle diffusion-controlled with an evident influence of liquid film diffusion. These results suggest that mSGT-DETA is a promising sorbent for Re(VII) ions removal from aqueous solutions.
