“…Several other publications have also addressed EME of different basic drugs, including amlodipine enantiomers, 20 mebendazole, 21 amphetamine, 22 methamphetamine, 22 3,4-methylenedioxymethamphetamine, 22 3,4-methylenedioxyethamphetamine, 22 methylbenzodioxolybutanamine, 22 levamisole, 23 lithium, 24 naltrexone, 19 and nalmefene. 19 In these applications either NPOE, 20,21 1-octanol, 24 NPOE mixed with DEHP, 19 or NPOE mixed with tris-(2-ethylhexyl) phosphate (TEHP) 22,23 were used as SLM, and extractions were accomplished with voltages in the range 75 -250 V from acidic sample to acidic acceptor solution.…”

“…For non-polar basic analytes, NPOE has been found to be very efficient 10,20,21 whereas addition of carriers or SLM modifiers like DEHP or TEHP was required for extraction of more polar basic substances. 16,19,22,23 Other solvents like 1-ethyl-2-nitrobenzene (ENB), NPPE, and IPNB have also been found efficient for non-polar basic drugs. 25,35 For acidic analytes in contrast, 1-octanol has proven to be an efficient SLM, 26 whereas 1-octanol with DEHP has worked efficiently for EME of peptides.…”

“…Basically, the analyte should be charged both in the sample and in the acceptor phase for electro-kinetic migration, and pH conditions should be selected to ensure this. Thus, basic substances (and peptides) have been extracted in acidic environment, typically using HCl as background electrolyte in both the sample and in the acceptor phase, 10,17,[20][21][22][23]25,27 but also HCOOH has been used as a MS friendly acceptor phase. 18,33 Acidic substances on the other hand have been extracted under alkaline conditions using NaOH as background electrolyte.…”

The presence of pharmaceutical pollutants in water sources constitute a serious risk to human health and the environment. Catalytic ozonation has emerged as a promising strategy for reducing these pollutants. This procedure uses ozone with the help of catalysts to improve the oxidation of organic molecules. Recently, there has been a lot of interest in using zeolite as an ozonation catalyst in the elimination of pharmaceutical contaminants from water solutions. Zeolites have unique properties such as their high surface area, porosity, and ion‐exchange capabilities, that make them effective catalysts for the decomposition of ozone and the oxidation of organic pollutants into harmless byproducts. This study aims to investigate the efficiency of zeolite catalytic ozonation in the elimination of pharmaceutical pollutants from aqueous solutions encompassing the working mechanisms, the determinants affecting the process's efficiency, potential obstacles, and perspective avenues for advancement within this field.

A novel pH-responsive block copolymer (Poly ethylene glycol-b-poly (N,N-dimethylaminoethylmethacrylate-co-maleic acid) was designed for the decoration and stabilization of magnetic nanoparticles (MNPs) as an efficient magnetic nano adsorbent for extraction of amphetamine (AM) from biological urine samples to be determined by high performance liquid chromatography-ultra violet detector (HPLC-UV). Full characterization of the synthesized polymeric magnetic nanoparticles (PMNPs) were followed by various techniques like Fourier transform infrared (FT-IR) spectroscopy, powder x-ray diffraction (XRD), scanning electron microscopy (SEM), and vibrating sample magnetometer (VSM). Important extraction parameters including pH, amount of sample volume, amount of adsorbent, type and amount of extraction organic solvent, time of extraction and desorption, agitation rate (rpm), and ionic strength of the extraction medium were studied and optimized. Under optimized extraction conditions, good linearity was observed in the concentration range of 30-2000 ng/mL for AM. The amount of the q was calculated as 0.18 (mg/g). The method was applied in determination of AM from positive urine samples with the recovery of 99.84%. Results indicated that the proposed method could be applied in clinical and forensic laboratories for simple, selective, and fast determination of AM from urine samples.
