“…First, 2 mmol of Pb(NO3)2 was dissolved in 25 mL DMF under ultrasonic oscillation. Then 4 mmol BPHA, 8 mmol 4-vynil pyridine and 25 mL methanol were added to the solution and stirred overnight at room temperature 25 . After that, 0.5 g Fe3O4@SiO2-APS-MA, 8 mmol EGDMA and 0.1 g AIBN were added to the solution and reacted at 60 °C for 24 h under nitrogen atmosphere.…”

A magnetic Pb(II) ion-imprinted polymer was synthesized using magnetic Fe3O4@SiO2 nanospheres as supporter, n-benzoyl-n-phenyl hydroxylamine as ligand, 4-vinyl pyridine as monomer, ethylene glycol dimethacrylate as crosslinker and 2,2′-azobis(isobutyronitrile) as the initiator. The template was removed from the polymer using 4 mL of HCl (2 mol L-1). The chemical structure, morphology-particle size, elemental analysis, thermal behavior and magnetic properties of the sorbent were evaluated using Fourier-transform infrared spectroscopy, scanning electron microscopy & ImageJ software - Energy dispersive X-ray system, thermal gravimetric analysis and vibrating sample magnetometry. Various parameters such as pH, equilibrium extraction time, temperature and the eluent were optimized. The results showed the sorbent adsorption capacity was 92.3 mg g-1 in pH 6.0 media, equilibrium time of 7 min at 40 °C. Calibration linearity was 2-150 µg L-1 with detection limit of 0.3 µg L-1. The prepared sorbent had high selectivity and was successfully applied to the removing of lead in real samples.

This study was conducted to determine the optimum extraction conditions for the effective separation and removal of Cu2+, Fe2+, and Fe3+ using N-benzoyl-n-phenylhydroxylamine (BPA) as an analytical reagent. An efficient liquid-liquid extraction method was developed for the separation and removal of Cu2+, Fe2+, and Fe3+ from environmental waste samples. In this method, BPA was used as a chelating agent and the effect of different parameters- including solvents, pH, stripping agents, extraction time, and the interference of other ions- on the quantitative removal of these metals was investigated. This study demonstrates that chloroform is the most effective solvent for BPA. The maximum extraction of the selected metallic species was found between pH 3 and 5. It was demonstrated that the maximum percentage recovery of the metals can be attained using 1 M HCl as a stripping agent. Optimized conditions of different parameters could be beneficial for industry and environmental laboratories.
