In the present study, a polymeric nanocomposite, CoFe2O4@DHBF, was fabricated using 2,4 dihydroxybenzaldehyde and formaldehyde in basic medium with CoFe2O4 nanoparticles. The fabricated nanocomposite was characterized using FTIR, TGA, XRD, SEM, TEM, and XPS analyses. The analytical results revealed that the magnetic nanocomposite was fabricated successfully with high surface area 370.24 m2/g. The fabricated CoFe2O4@DHBF was used as an efficient adsorbent for the adsorption of U(VI) and Eu(III) ions from contaminated water. pH, initial concentration, adsorption time, and the temperature of the contaminated water solution affecting the adsorption ability of the nanocomposites were studied. The batch adsorption results exposed that the adsorption capacity for the removal of U(VI) and Eu(III) was found to be 237.5 and 225.5 mg/g. The adsorption kinetics support that both the metal ions follow second order adsorption kinetics. The adsorption isotherm well fits with the Langmuir adsorption isotherm and the correlation coefficient (R2) values were found to be 0.9920 and 0.9913 for the adsorption of U(VI) and Eu(III), respectively. It was noticed that the fabricated nanocomposites show excellent regeneration ability and about 220.1 and 211.3 mg/g adsorption capacity remains with U(VI) and Eu(III) under optimum conditions.

In present study, graft copolymer was synthesized by free radical method using N-tertiary butylacrylamide monomer on chitosan which is an environment friendly polymer. The chemical structure and the surface morphology of the newly synthesized graft copolymer were determined by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), and X-ray diffraction (XRD). Thermal behavior was analyzed by thermogravimetric analysis (TGA). To investigate the applicability of chitosan-graft-poly(N‑tert‑butylacrylamide) graft copolymer, it was used as an adsorbent for rapidly removal of tetracycline from aqueous solution. Response surface methodology (RSM) was employed for the optimization of the study conditions such as adsorbent dosage (0.01–0.04 g), reaction time (10–90 minutes), and initial tetracycline concentration (10–100 mg 100 mL− 1). The effects of these conditions on tetracycline uptake capacity were examined by RSM and the results were statistically analyzed. The RSM results showed that maximum tetracycline uptake capacity (104.81 mg g− 1) was achieved at the adsorbent dose of 0.03 mg 100 mL− 1, reaction time of 51.12 minutes, and initial tetracycline concentration of 97.99 mg L− 1. ANOVA analysis based on central composite design combined with RSM showed good agreement between experimental values and quadratic model estimates, thus resulting in 0.9118 R2 for tetracycline uptake. The findings demonstrated chitosan-graft-poly(N‑tert‑butylacrylamide) copolymer is an effective adsorbent for pharmaceutical wastewater treatment.
