In recent years, there has been a growing interest in plant pigments as readily available nutraceuticals. Photosynthetic pigments, specifically chlorophylls and carotenoids, renowned for their non-toxic antioxidant properties, are increasingly finding applications beyond health-promoting attributes. Consequently, is an ongoing need cost-effective methods of isolation. This study employs co-precipitation method to synthesize magnetic iron oxide nanoparticles. Scanning electron microscopy (SEM) coupled with energy dispersive spectrometry (EDS) confirms that aqueous environment oxidizing conditions yield nanosized particle sizes ranging from 80 140 nm. X-ray photoelectron spectroscopy (XPS) spectra indicate the presence hydrous FeO(OH) on surface oxide. The Brunauer–Emmett–Teller (BET) area obtained nanomaterial was 151.4 m2 g−1, total pore volumes pores 0.25 cm3 g−1 STP. material, designated nanoparticles (IONPs), serves adsorbent solid phase extraction (MSPE) isolation photosynthetic (chlorophyll a, lutein) extracts higher green plants (Mentha piperita L., Urtica dioica L.). Sorption chlorophyll onto confirmed using UV–vis spectroscopy, Fourier transform infrared photoacoustic (FT-IR/PAS), high-performance liquid chromatography (HPLC). Selective sorption requires minimum 3 g IONPs per 12 mg acetone solvent, dependent storage time 48 h. Extended contact extract, i.e., 72 h, ensures elimination remaining components except lutein, spectral purity 98%, recovered over 90% efficiency. mechanism removal relies interaction pigment’s carbonyl (C=O) groups hydroxyl (–OH) groups.
