摘要: Abstract This study aims to research the adsorption of Nd+3, Tb+3, and Dy+3 from aqueous media onto magnetic calcium alginate/carboxymethyl chitosan/Ni0.2Zn0.2Fe2.6O4 (CA/CMC/Ni0.2Zn0.2Fe2.6O4) bionanocomposite in a single system. FE-SEM, FT-IR, EDX, VSM, TGA were applied characterize product. The VSM result showed saturation magnetization values 45.87 14.14 emu/g for bare Ni0.2Zn0.2Fe2.6O4 nanoparticles CA/CMC/Ni0.2Zn0.2Fe2.6O4, respectively. results that at optimum conditions contact time 40 min, pH 5.5, 0.8 g/L, efficiency adsorbent was 97.75, 96.83, 97.85%, ions kinetic CA/CMC/Ni0.2Zn0.2Fe2.6O4 accordance with pseudo-second-order (PSO) model. evaluation equilibrium data performed by isotherm models Langmuir Freundlich. Fitting experimental Tb+3 done better Freunlich model than model, while fitting tests Nd+3 coverage using maximum capacity 73.37 mg/g. parameters thermodynamic endothermic spontaneous properties process. Additionally, efficacy studied 0.2 M HNO3 four adsorptions–desorption cycles. Overall, obtained demonstrated environmentally friendly can be effectively favorable efficiency.
