It can be combined with various detectors, of which mass spectrometry (MS) and flame ionization detector (FID) are the most common. The MS is used for structure determination and conformation, while FID is more suitable for quantitative analysis. Therefore, these two detectors are often coupled together in one system. Depending on the nature of the sample and analyzed compounds, sample preparation and method conditions will be selected. Volatile and stable compounds, such as terpenes, can be analyzed directly after dissolving them in a suitable solvent. On the other hand, some less stable compounds (acidic forms of cannabinoids) and non-volatile (polyphenolic compounds) must be derivatized (usually silylation) before the analysis to increase their stability and volatility. The physico-chemical properties of the analyzed compounds will also influence the choice of column and temperature program on the GC. Based on the stationary phase, the capillary column may be non-polar, mid-polar, or polar. Compounds such as cannabinoids and polyphenolic compounds are analyzed on non-polar columns, while terpenes and alcohols are analyzed on mid-polar and polar columns. The nature of fatty acid methyl esters (FAMEs) allows their analysis on mid-polar and polar columns. However, for optimal separation, the most polar columns are used, where even <em>cis</em> and <em>trans</em> isomers can be separated. Selecting the method is not an easy task, and this article provides helpful information for method selection and sample preparation.</div></div>","PeriodicalId":56032,"journal":{"name":"Trends in Environmental Analytical Chemistry","volume":"49 ","pages":"Article e00295"},"PeriodicalIF":13.4,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145839972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review explains the outlines of recent advancements in electrochemical sensing methods, with a focus on metal oxide electrodes. These electrodes have been recognized as promising platforms for microplastic detection owing to their relatively high chemical stability, large surface area, and superior conductivity. Various metal oxides, such as zinc oxide (ZnO), titanium dioxide (TiO₂), and iron oxide (Fe₃O₄), have been investigated for their suitability in these applications. This review discusses the principles and mechanisms underlying electrochemical sensing, including voltammetric and amperometric techniques. Key factors influencing the performance of metal oxide-based sensors, such as electrode morphology, surface functionalization, and sensor configuration, are examined. Recent developments in sensors, fabrication techniques, and strategies for enhancing sensitivity and selectivity are also highlighted. In addition, the review confronts the challenges, hurdles, and future directions in electrochemical sensing for microplastic detection, including the need for standardized protocols, validation of sensor performance in real-world samples, and integration into monitoring networks for environmental surveillance.

In response, green and natural materials have emerged as attractive alternatives for both contaminant removal and water quality monitoring, offering advantages such as biodegradability, ecological safety, cost-efficiency, and wide availability. This review provides a detailed overview of recent advancements in utilizing plant-based adsorbents, agricultural and industrial bio-wastes, natural polymers, clays, algae, microbial biomass, and eco-friendly nanomaterials for water purification. It explores key removal strategies including adsorption, photocatalytic degradation, membrane filtration, bio-based coagulation-flocculation, and bioremediation, demonstrating their effectiveness in targeting heavy metals, organic pollutants, biological contaminants, microplastics, and newly recognized environmental toxins.

Natural enzymes, as efficient catalysts produced in living organisms, can be applied to the detection and sensing of pollutants through their mediated enzymatic reactions. However, the poor environmental stability, complex purification techniques, and high costs of natural enzymes have limited their large-scale application in environmental analysis. Nanozymes, as a class of nanomaterials with enzyme-like activity, are characterized by high catalytic activity, good stability, low cost, and easy production and preparation. Most nanozymes use transition metals as catalytic active sites. Since copper has multiple oxidation states, nanozymes with copper as the active center typically exhibit multiple activities, particularly some copper-based nanozymes that possess oxidase-like activity, whose catalytic action relies on oxygen. This characteristic has enabled their broader application in environmental analysis (e.g., rapid detection and identification of environmental pollutants). This review discusses the classification of enzyme-like activities of copper-based nanozymes and their design strategies, composition types, and various applications in the field of environmental analysis (rapid detection and identification of environmental pollutants) based mainly on the research of copper-based nanozymes for the analysis of environmental pollutants in the last three years, and summarizes the current status of copper-based nanozymes in environmental analysis (their effectiveness in detecting and identifying environmental pollutants), challenges (low sensitivity, poor selectivity, lack of rational design), and future trends (integration with electrocatalysis, molecular imprinting technology, and rational design based on target substance characteristics). We link the activity of copper-based nanozymes with their corresponding design strategies and discuss approaches to yield copper-based nanozymes with a range of activities.
