Given the intricate nature of sample matrices and the low concentrations of these compounds, the utilization of more sensitive and reliable techniques is imperative for sample preparation. Microextraction, characterized by its high efficiency and stability for environmentally friendly analysis, has demonstrated superiority in various studies and has shown advancements in structural design and the application of novel materials in recent years. This review provides a comprehensive overview of recent advancements in microextraction techniques for the analysis of SMs, focusing on different sample types from 2017 to 2023. The applications of different microextraction techniques in different samples are summarized, highlighting both the major advancements and notable limitations. The discussed techniques include directly immersion solid-phase microextraction, headspace solid-phase microextraction, stir bar sorptive microextraction, thin film microextraction, fabric phase sorptive extraction, and dispersive solid-phase microextraction. Liquid phase microextraction methods, such as hollow fiber liquid-liquid microextraction, dispersive liquid-liquid microextraction, vortex-assisted liquid-liquid microextraction, and ultrasound-assisted electronic membrane extraction, provide alternative approaches for analyzing complex samples.

This requires timely monitoring and prediction of fluoroquinolone and metabolite changes. The physiochemical flexibility of fluoroquinolones, complicated sampling combinations, and matrix interference in sample preparation and detection could give misleading quantifying results. These complex and massive data sets require rigorous statistical and mathematical data processing approaches to detect analytical fingerprints/patterns, and point - nonpoint source discrimination. This paper has critically reviewed the use of predictive and exploratory chemometric models to identify the patterns and resolve overlapping, asymmetric peaks and multicollinearity fluoroquinolone spectrum data raised from several separative and non-separative detection techniques. Moreover, this review also highlights the crucial parameters involved in determining fluoroquinolones in real-time samples, challenges, and research gaps associated with current analytical techniques. The approach also prioritises the integration of clustering, classification and regression-based chemometrics to achieve justifiable accurate results.

Magnetic molecularly imprinted polymers (MMIPs) have benefits over traditional molecular imprinted polymers (MIPs) in sample pretreatment because of their larger specific surface areas and highly accessible particular binding sites, which result in excellent specificity and selectivity toward analytes. MMIPs are easily separated from a variety of complicated matrices and have a high adsorption capability. They play an essential role in the efficient extraction of various analytes from a variety of matrices, including water, soil, food and its derivatives, plant extraction, fruits and vegetables, and various biological samples. Additionally, MMIPs have the major benefit of being a green chemistry approach, whether in synthesis or applications; as a result, they effectively reduce pollution in the environment and minimize the use of resources. A variety of MMIP applications from 2019 to 2023 were reviewed in this work. The various approaches and procedures utilized to create MMIPs are covered in this review. In addition, a brief description of several MMIP-based analytical techniques is provided in this manuscript, along with information on various aspects such as their adsorption capacity, equilibrium time, limit of detection, extraction recovery, and recyclability assessment. The types of porogen and functional monomer used have the greatest effect on the efficiency and reusability of the constructed MMIPs. On the contrary, the cross-linker type has no prominent effect on the efficiency and reusability of the constructed MMIPs. Future opportunities and current obstacles to better promote MMIPs features are also covered. This publication served as a comprehensive assessment of a number of analytes in various matrices recovered by MMIP, including pollutants, dyes, natural components, pesticides, herbicides, and insecticides.

Surface runoff from their widespread use pollutes water and soil. Pesticides deplete beneficial insect populations, upset ecological equilibrium, and contaminate food chains, posing health concerns through bioaccumulation and biomagnification. Moreover, heavy metals from industry, mining, and inappropriate waste disposal are persistent, harmful environmental pollutants. Lead, mercury, cadmium, and arsenic in soils and sediments pollute water supplies and endanger aquatic life, wildlife, and humans. Heavy metal exposure can cause neurological issues, reproductive abnormalities, and cancer, making cleanup necessary. Also, industrial activities, wastewater discharge, and agricultural runoff produce phenolic compounds, another harmful environmental contaminant. Bisphenol A, phenol, and chlorophenols poison aquatic species, limit plant photosynthesis, and alter microbial populations. Additionally, phenolic chemicals can stay in the environment for lengthy durations, causing long-term ecological damage and health concerns from tainted drinking water and food. As a result, environmental monitoring is becoming increasingly important for sensitively detecting and quantifying pesticides, phenolic compounds, and heavy metals. Electrochemical sensors and modification materials are prepared for specific pollutant detection, providing selectivity and sensitivity, thus enabling the detection of the target molecule down to the nanomolar or even picomolar range. In this respect, ordered mesoporous carbon (OMC) materials attract attention in electrochemical sensing applications due to their numerous advantages. OMCs are promising for catalysis and sensing applications due to their well-ordered pore structure, high specific surface area, and tunable pore sizes in the mesopore range. The unique properties of these materials could open a new approach to studying the electrochemical determination of other environmental pollutants.

Additionally, the composition of DOM can vary based on the source water quality and the specific treatment processes employed. Advanced analytical techniques, such as non-targeted analyses using ultrahigh- or high-resolution mass spectrometry [(U-)HRMS], are improving our understanding of the nature of specific organic compounds present in DOM and their potential to form DBPs.
