In this study, a magnetic waste-tyre derived activated carbon modified with methyltrioctylammonium chloride, was successfully synthesized, characterised, and applied for the extraction and preconcentration of four non-steroidal anti-inflammatory drugs in wastewater. The SEM and N2-adsorption/desorption anal. results confirmed that the synthesized nanocomposite was porous with a large sp. surface area of 570 m2 g-1. The significant factors affecting the Ultrasonic assisted magnetic solid phase extraction method were investigated using univariate approach and response surface methodol. The optimum conditions for the extraction and preconcentration of the target analytes were 0%, 15 min, 6.5 and 30 mg, for ionic strength, extraction time, pH and adsorbent mass resp. The quantification of the target analytes was performed using high performance liquid chromatog. equipped with diode array detector. Under optimum conditions, low limits of detection and quantification ranging between 0.054-0.38μg L-1 and 0.18-1.27μg L-1, resp., were obtained. A wide linearity (ranging from limit of detection – 500μg L-1 with R2 ≥ 0.99) and precision lower than 7%, were achieved. The applicability of proposed method was evaluated for the determination of naproxen, ketoprofen and diclofenac in wastewater. This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3Computed Properties of C25H54ClN).
N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3) belongs to organic chlorides. Organic chlorides can be used in production of: PVC, pesticides, chloromethane, teflon, insulators. Alkyl chlorides readily react with amines to give substituted amines. Alkyl chlorides are substituted by softer halides such as the iodide in the Finkelstein reaction.Computed Properties of C25H54ClN
