Abstract:
In this study, magnetic pomelo peel‐derived biochar composite was fabricated and applied as a low‐cost adsorbent for the simultaneous extraction of morphine‐like opioids named morphine, codeine, and 6‐monoacetylmorphine from wastewaters, prior to their determination via liquid chromatography‐mass spectrometry. A total of four biochar products were synthesized under different pyrolytic temperatures of 400, 500, 600, and 700°C, respectively, and the 400°C biochar was found to have the greatest extraction ability, with enrichment factors of 34, 58, and 61 for the three drugs. The primary adsorption mechanism includes π‐π interaction and H‐bonding. Parameters affecting the extraction of opioids were optimized. Under optimum conditions (such as pH = 7; adsorbent amount = 15 mg; sample volume = 20 ml; eluent solvent, 200 µl of methanol), the method was proved to be linear in the range of 0.05–10.0 µg/L, with coefficients of determination greater than 0.99, and the limits of detection were 0.006–0.010 µg/L. In‐batch and inter‐batch precisions were 1.8%–6.5% and 4.8%–10.6%, respectively. The method was successfully applied to the determination of the target opioids in the samples of influent and effluent wastewater. The developed method by using magnetic pomelo peel‐derived biochar could potentially be applied for the effective estimation of illicit drug consumption.
