Novel hydrophobic deep eutectic solvents for ultrasound-assisted dispersive liquid-liquid microextraction of trace non-steroidal anti-inflammatory drugs in water and milk samples

Remediation of pharmaceuticals from contaminated water by molecularly imprinted polymers: a review

“…Non-steroidal anti-inflammatory drugs such as diclofenac, potassium diclofenac, naproxen, and ketoprofen, with their concentration up to μg L −1 , may be enough to cause toxic effects that can often be located in water sources (Qiao et al 2021 ). As persistent toxic pollutants in the environment, diclofenac and its derivatives can cause serious damage to human livers, kidneys, and affect the growth of microorganisms even at very low concentrations (Amaly et al 2021 ; Bi et al 2021 ).…”

Density-adjusted liquid-phase microextraction with smartphone digital image colorimetry to determine parathion-methyl in water, fruit juice, vinegar, and fermented liquor

“…The volume of the extractant has a critical role in the recovery of analytes. 31 The experiment investigated the effect of different volumes of guaiacol (50, 75, 100, 125, 150, 175, and 200 μL) on the extraction efficiency ( Fig. 2 ).…”

Overview of Different Modes and Applications of Liquid Phase-Based Microextraction Techniques

“…However, as a result of health threats such as cardiovascular complications, cerebrovascular risks, and gastrointestinal ulcers posed by their presence in the environment, they have been tagged as 'emerging pollutants' [27,28]. The development of a method for the isolation of four NSAIDs was investigated by Qiao et al [29]. The extraction process involved the transfer of 10 mL of the sample spiked with 1 µg mL −1 each of diclofenac and oxaprozin, 2 µg mL −1 of ibuprofen, and 1.5 µg mL −1 of salicylic acid before the addition of 200 µL of the synthesized HDES.…”

“…Hydrophobic DESs and NADESs are liquids at room temperature and have been increasingly used in all modes of LPME as green solvents [45]. Qiao et al [29] extracted NSAIDs in environmental water and milk samples through an ultrasound-assisted DLLME method (Table 1). The hydrophobic DES was composed of guanidinium chloride and thymol, and the results showed the potential of the synthesized DES with low limits of detection of 0.5-1 µg L −1 and acceptable recoveries in the range of 79.42%-107.52%.…”
