Stereoselective chiral molecules are responsible for specific biological functions in nature. At present, more than half of the prescribed drugs are chiral. Living organisms display divergent pharmacological responses to the enantiomers, leading to altered toxicity, pharmacokinetics, and pharmacodynamics. Thus, chiral analysis, separation, and extraction are crucial for ensuring enantiomeric purity to develop safe and effective medication. In recent times, metal–organic frameworks (MOFs) with appealing structures are gaining importance because of their fascinating properties as a sorbent and stationary phase. MOFs are crystalline porous solid materials built by interconnecting metal ions or clusters and organic linkers. This review explores the advancements in MOFs for the isolation and separation of chiral active pharmaceutical drugs.

“…Various types of adsorbents [65][66][67] and formats [51,63,65] have been reported in the literature and they cover all potential interactions with the analytes [63,64]. This study will briefly review the application of MOFs in traditional SPE, DSPE, micro SPE (µ-SPE), pipette tip SPE (PT-SPE) and MSPE for environmental analysis.…”

In counties like South Africa, firstly, the waste PET stream has posed a serious problem to the environment, and the current recycling of waste PET remains as low as 30%. The waste PET recycling industries such as PETCO & Extrupet (South Africa) are struggling to implement innovative processes to make cooperate more profitable. Secondly, metal-organic frameworks (MOFs) as a new class of porous materials, the MOFs-based water treatment holds the promises to provide cost-effective solutions dealing with the polluted water. However, the high costs of MOFs production have raised a challenge for its effective implementations. Given that, cross-cutting advances in materials and engineering will help to solve those societal challenges. To maintain the world-class research and development associated with human capacity in South Africa, this multidisciplinary and transdisciplinary work has been strengthened along with the basic-applied research continuum under the frame of South Africa (NRF)/Poland (NCBR) Joint Science and Technology Research Collaboration.

“…As with other adsorption formats [14][15][16][17], FMNPs are the kernel of MSPE because they can affect the extraction performance of analytes significantly. So far, all kinds of materials such as carbon-based materials [18,19], molecularly imprinted polymers [20], metal-organic frameworks [21,22], and covalent organic frameworks [23] have been introduced to modify magnetic cores (typically, Fe 3 O 4 ). Although there are various adsorbents for MSPE, however, to efficiently capture different kinds of analytes, task-specific FMNPs should be designed and prepared according to the properties of targeted analytes.…”

Efficient enrichment is a challenging and indispensable step in the quantification of polar synthetic auxins in complex samples. In the current study, a new magnetic adsorbent based on polymeric ionic liquid/aminated carbon nanotube composite was fabricated with a one-pot precipitation copolymerization strategy and employed as the extraction phase of magnetic solid phase extraction of synthetic auxins. Various characterization techniques were utilized to inspect the morphology, structure, magnetic property, and functional groups of the prepared adsorbent. Under the optimal conditions, the obtained adsorbent displayed satisfactory capture performance towards studied auxins through multiple interactions. Adsorption studies evidenced that the adsorption procedure of the developed method towards analytes was fit for the Freundlich adsorption model and pseudo-second-order kinetics. Combining with high-performance liquid chromatography, sensitive and reliable method for the identification and quantification of trace synthetic auxins in environmental water and fruit juice samples was developed. The obtained limits of detection for water and fruit juice samples located in the ranges of 0.0059-0.013 and 0.018-0.031 μg/L, respectively. Recoveries in actual samples with different fortified contents varied from 82.2% to 117%, with satisfactory reproducibility. The results will evidence that the introduced extraction technique is a useful alternative for the entrapment of trace synthetic auxins from complex samples.
