Abstract

Sample preparation plays a pivotal role in chemical analysis, serving to isolate target analytes from diverse matrices and enhance measurement selectivity and sensitivity. This review examines microextraction's eco-friendliness versus tradition, focusing on LPME and EME systems for acidic compounds. Different solid supports (polymeric and gel membranes) implemented in different configurations are evaluated. These innovative techniques reduce the consumption of chemicals and offer enhanced environmental safety. To determine the greenness of these techniques, we employ three widely recognized metrics: Analytical Eco-Scale, Green Analytical Procedure Index (GAPI), and Analytical GREEnness (AGREE). Our comparative analysis provides insights into the strengths and weaknesses of these metrics and offers a holistic perspective on the greenness of microextraction techniques. This review contributes to the ongoing efforts in Green Analytical Chemistry by facilitating the selection of environmentally benign sample preparation methods, thus promoting sustainable laboratory practices, and minimizing adverse environmental impacts.

基于聚合物膜和凝胶膜作为固体支持物的微萃取技术的分析绿色指标比较评估

样品制备在化学分析中起着举足轻重的作用，它有助于从不同的基质中分离出目标分析物，并提高测量的选择性和灵敏度。本综述探讨了微萃取的生态友好性与传统性，重点关注酸性化合物的 LPME 和 EME 系统。对不同配置的固体支持物（聚合物膜和凝胶膜）进行了评估。这些创新技术减少了化学品的消耗，提高了环境安全性。为了确定这些技术的绿色程度，我们采用了三个广受认可的指标：分析生态尺度（Analytical Eco-Scale）、绿色分析程序指数（GAPI）和分析绿色度（AGREE）。通过比较分析，我们深入了解了这些指标的优缺点，并从整体角度分析了微萃取技术的绿色性。本综述有助于选择对环境无害的样品制备方法，从而促进可持续的实验室实践，并最大限度地减少对环境的不利影响，为绿色分析化学的持续发展做出贡献。
