Ibuprofen degradation using a Co-doped carbon matrix derived from peat as a peroxymonosulphate activator

摘要: Abstract The wider presence of pharmaceuticals and personal care products in nature is a major cause for concern society. Among pharmaceuticals, the anti-inflammatory drug ibuprofen has commonly been found aquatic soil environments. We produced Co-doped carbon matrix (Co–P 850) through carbonization Co2+ saturated peat used it as peroxymonosulphate activator to aid degradation. properties Co–P 850 were analysed using field emission scanning electron microscopy, energy filtered transmission microscopy X-ray photoelectron spectroscopy. characterization results showed that Co/Fe oxides generated tightly embedded into after carbonization. degradation indicated high temperature slightly acidic neutral conditions (pH = 5 7.5) promoted efficiency 850/peroxymonosulphate system. Analysis approx. 52% 75% dissolved organic was removed 2 h 5 h reaction time, respectively. Furthermore, existence chloride bicarbonate had adverse effects on ibuprofen. Quenching experiments paramagnetic resonance analysis confirmed SO4·-, ·OH O2·− radicals together contributed efficiency. In addition, we identified 13 intermediate compounds an pathway by mass spectrometry quantum computing. Based methods presented this study, propose novel way synthesis catalyst from spent NaOH-treated efficient catalytic contaminated water.
