The antibiotic sulfamethoxazole (SMZ) is an emerging organic contaminant of concern. Residual amounts of this contaminant have been reported at different concentrations in aquatic environments due to the inability of wastewater treatment plants to remediate this compound completely. In this study, a classical polymer inclusion membrane (PIM) comprised of the base polymer cellulose triacetate (CTA), the carrier Aliquat 336, and the plasticiser dioctyl phthalate (DOP) was used for SMZ remediation. After an extraction time of 40 h at pH 9, the PIM completely removed SMZ with a transport efficiency of 82%. In order to improve the transport of SMZ across the membrane, we investigated the impact of an elec. voltage through electromembrane extraction (EME) at 20-120 V. At an extraction time of 15 h and a voltage of 50 V, SMZ was removed completely with a transport efficiency of 100%. However, excessive bubbling at the electrode under higher voltages (≥70 V) led to membrane instability. Subsequently, the stability of the membrane was investigated by subjecting the same membrane to 12 cyclic mass transfers under the same conditions; there was a slight difference in the efficiencies of the membrane. A gradual loss of membrane mass was recorded after each exptl. cycle, attributed to the loss of the membrane liquid phase. Finally, the fabricated PIM was successfully used to preconc. SMZ from real environmental samples, with preconcentration factors ranging from 22.9-24.1. Hence, applying a voltage was essential to achieving the total recovery of SMZ. This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3Recommanded Product: N-Methyl-N,N-dioctyloctan-1-aminium chloride).
N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning. The hydrocarbon processing industry (HPI) and others are affected by damage caused by these substances. 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.Recommanded Product: N-Methyl-N,N-dioctyloctan-1-aminium chloride
