“…The limit of quanti cation (LOQ) and limit of detection (LOD) are dependent on the sample matrix [51]. In this work, to study the impact of the matrix, 100 mL of drinking water, river water, Milli-Q water, and wastewater were spiked with 20 µL of 5000 µg L -1 MCs standard solution, and the nal concentration after spiking was 1 µg L -1 .…”

Cyanobacteria, an algae bloom that is responsible for the creation of deadly toxins. These toxins have the potential to adversely impact human and animal health. Microcystins (MC’s), are harmful toxins that are produced by cyanobacteria species. These deadly toxins are the most investigated toxins worldwide. However, in South Africa their occurrence statistics are deficient due to inaccessibility of reliable, sensitive, and precise analytical methods to investigate them in water surfaces. Thus, a development of analytical methods for the detection and accurate quantification of algal toxins is crucial to consider the health risk of exposure to toxins in wastewater and surface waters. This study recommends an analytical method for the detection and quantification of algal toxins using solid phase extraction (SPE) and high-performance liquid chromatography (HPLC) coupled with photodiode detector (PDA). The developed method was validated based on linearity which ranged from 3–2500 µg L− 1, recoveries at 99.6–113.9%, the limit of detection (LOD) ranging from 0.2–480 µg L− 1, and limit of quantification (LOQ) at 0.7–160 µg L− 1 and the regression coefficients obtained were above 0.9880 in all analytes. The developed method was applied to Darvill Wastewater Treatment Plant, Umgeni water, Durban surface waters, University of KwaZulu-Natal (UKZN) sport centre tap water and UKZN Westville two ponds), South Africa. MC-RR was the most detected analyte at concentration ranging from 0.069–30.521 ng L− 1 compared to other targeted MCs. The developed method is simple and cheap, which can consent developing countries to monitor these deadly MC toxins in water surfaces.

“…A very good example of such a type of extraction was presented by Tuzen et al [ 30 ]. In this research, the polystyrene-polyricinoleic acid copolymer containing silver NPs (AgPSrici) was created and applied in the separation of molybdenum ions from different aqueous and food samples during the DSPME approach.…”

The aim of this work focuses on the application of nanomaterials (NMs) in different sorptive extraction techniques for the analysis of organic contaminants from environmental samples of distinct matrix compositions. Without any doubt, the integration of specific NMs such as carbonaceous nanomaterials, magnetic nanoparticles (MNPs), metal–organic frameworks (MOFs), silica nanoparticles, and ion-imprinted NPs with solid-phase extraction techniques counting d-SPE, solid-phase microextraction (SPME), and stir bar sorptive extraction (SBSE) impact on the improvements in analytical performance. The application of NMs as sorbents in the extraction of organic pollutants in environmental samples allows for providing better sensitivity, repeatability, reproducibility, and reusability.

“…Among different heavy elements, cadmium, lead, and inorganic arsenic are critical because of their association with numerous health issues, including impaired brain development in children, cardiovascular diseases, cancer, , kidney malfunctions, and various neurological impacts that are still under investigation. , While there are efforts to reduce the release of these elements, which is primarily due to human activities such as farming and industrial processing, , it is equally important to know how much exposure humans receive through the consumption of food and water. Several analytical methods, including solid-phase extraction (SPE), − have been developed to determine the content of heavy metals, which are generally present at trace levels in real-life samples. − One of the SPE family members is dispersive micro solid-phase extraction (d-μ-SPE), ,− which benefits from both high dispersions of the solid phase for better extraction and the utilization of the solid phase in the “microgram” regime.…”

“…The same group also developed a magnetic composite material based on graphene oxide (GO) and successfully extracted heavy metals using a new family of SPE methods called vortex-assisted magnetic solid-phase extraction . There are numerous examples of materials that were employed as solid phases in SPE methods, such as commercially available or synthesized polymers, nanoparticle-loaded composites, transition metal carbides, and many others. Here, we demonstrate the efficient use of NH 2 /SH-Ti 3 C 2 T x MXene as the solid phase in ultrasonic-assisted d-μ-SPE for the detection of cadmium (Cd 2+ ) and lead (Pb 2+ ) ions in food and soil samples.…”

Surface functionalization of two-dimensional (2D) transition metal carbides, nitrides, and carbonitrides, also known as MXenes, is a powerful approach for modification of their physical and chemical properties for new applications. In this study, we demonstrate the synthesis of a bifunctional Ti3C2T x MXene modified with amine and thiol groups through a facile condensation reaction. We successfully employed the resulting NH2/SH-Ti3C2T x MXene as a solid phase in the ultrasonic-assisted dispersive micro solid-phase extraction (d-μ-SPE) method for the analytical determination of heavy metals at trace levels in food and soil samples. The prepared NH2/SH-Ti3C2T x MXene showed remarkable performance in the ultrasonic-assisted d-μ-SPE method with limits of detection of 0.12 and 2.30 ng mL–1, with linear dynamic ranges of 0.50–90 μg L–1 and 10–120 μg L–1 for cadmium (Cd2+) and lead (Pb2+) ions, respectively. Furthermore, the extraction efficiencies were greater than 97%, with a relative standard deviation of less than 3% for five separate batch experiments in the determination of 5.0 μg L–1 of Cd2+ and Pb2+. This study shows that NH2/SH-Ti3C2T x can be used as a simple, rapid, reliable, selective, and sensitive material in the d-μ-SPE method for the trace determination of Cd2+ and Pb2+ in soil and agricultural products. This study demonstrates the utility of MXenes for analytical chemistry and suggests that further advances in methods for the functionalization of MXenes can open new applications for these already exciting materials.
