“…Extraction time is defined as the contact time between the aqueous solvent and the tested analyte. Generally, extraction efficiency is time dependent and defined by the time required for distribution equilibrium to occur between the target analytes and the aqueous solution [33]. In this study, the effect of incubation extraction times ranging from 3 to 20 min were tested while the other variables royalsocietypublishing.org/journal/rsos R. Soc.…”

This work describes the development of a new methodology based on magnetic nanoparticles assisted dispersive liquid–liquid microextraction (DLLME-MNPs) for preconcentration and extraction of chloramphenicol (CAP) antibiotic residues in water. The approach is based on the use of decanoic acid as the extraction solvent followed by the application of MNPs to magnetically retrieve the extraction solvent containing the extracted CAP. The coated MNPs were then desorbed with methanol, and the clean extract was analysed using ultraviolet–visible spectrophotometry. Several important parameters, such as the amount of decanoic acid, extraction time, stirring rate, amount of MNPs, type of desorption solvent, salt addition and sample pH, were evaluated and optimized. Optimum parameters were as follows: amount of decanoic acid: 200 mg; extraction time: 10 min; stirring rate: 800 rpm; amount of MNPs: 60 mg; desorption solvent: methanol; salt: 10%; and sample pH, 8. Under the optimum conditions, the method demonstrated acceptable linearity ( R 2 = 0.9933) over a concentration range of 50–1000 µg l –1 . Limit of detection and limit of quantification were 16.5 and 50.0 µg l –1 , respectively. Good analyte recovery (91–92.7%) and acceptable precision with good relative standard deviations (0.45–6.29%, n = 3) were obtained. The method was successfully applied to tap water and lake water samples. The proposed method is rapid, simple, reliable and environmentally friendly for the detection of CAP.

“…This method shows promising results with higher yields, a reduction in the amount of template used and the involvement of simple synthesis steps. MIP has been applied as an adsorbent in the determination of trace-level pollutants in the environment such as water (Rozaini et al, 2019) and sediments (Duan et al, 2013)…”

“…The prime objective is to introduce new materials that are more selective and easily prepared, which can improve on the conventional methods. Advanced materials have been used in numerous applications such as the determination of parabens (Fumes & Lanças, 2016), sulfonamides (Rozaini et al, 2019), bisphenol A (Rozaini et al, 2017), triclosan (Alshishani et al, 2019), and endogenous steroids (Manaf et al, 2018) in both environmental waters and human urine. Another important objective is to reduce the consumption of organic solvents, which are used in large amounts in conventional liquid-liquid extraction (LLE).…”

The widespread presence of contaminants in water demands reliable and practical analytical methods to monitor them. However, before their determination, a sample pretreatment step is necessary. This has conventionally been performed using liquid-liquid extraction (LLE) or solid-phase extraction (SPE). Advances in material sciences have since been capitalized on, with new adsorbents used in conjunction with new sample pretreatment techniques based on microextractions. In this mini-review, we showcase some of our previously reported work that demonstrates how advanced materials such as graphene, molecularly imprinted polymers (MIPs), and polymeric cyclodextrins can be used as adsorbents for the determination of contaminants such as bisphenol A, steroids, sulfonamide antibiotics, and antimicrobial agents. These adsorbents formed an important component in the micro-solid phase extraction that was used for the pretreatment of the sample. A brief introduction to the adsorbents studied and evolution of extractions is provided. The distinctive features of the analytical methods used in the real sample analysis of the stated contaminants are highlighted.
