- Abstract
Global concern about pharmaceutical and endocrine disrupting compounds in water resources is at its most intense due to their adverse effects on human health and environmental sustainability. Polydopamine-coated magnetic nanoparticles (MNPs@PDA) and polypyrrole-coated magnetic nanoparticles (MNPs@PPy) were successfully synthesized with strong magnetic attraction for easy separation. Their binding efficiencies with bisphenol A (BPA), metformin (MF), naphthalene acetic acid (NAA), phenformin (PF), quinine sulfate (QS), and triclosan (TC) in water were determined using capillary electrophoresis with UV detection. At a concentration of 200 mg mL−1, the binding efficiencies of MNPs@PPy were found to be 99 ± 1% BPA, 34 ± 4% MF, 39 ± 6% NAA, 99 ± 1% PF, 98 ± 2% QS, and 99 ± 1% TC, whereas MNPs@PDA afforded 65 ± 5% BPA, 14 ± 6% MF, 21 ± 4% NAA, 99 ± 1% PF, 94 ± 2% QS, and 92 ± 3% TC. Hence, both MNPs@PDA and MNPs@PPy have a high capacity for efficient removal of aromatic compounds from water.
