The increasing concern about environmental degradation and resource depletion has inspired the analytical chemistry community to develop analytical methods that comply as much as possible with the principles of Green Analytical Chemistry. Significant progress has been made in greening sample preparation strategies by miniaturizing sampling devices and decreasing the amount of sorptive phase needed for efficient extraction of targeted molecules. In this context, the use of natural sorbents represents an additional and convenient option for green sample preparation. The advantages of using natural sorbents for extraction include their availability from renewable sources, low toxicity and biodegradability. In this review, we describe the use of various natural sorbents for metals and organic molecules extraction, focusing on the most innovative applications within the decade 2009-2019. Particular emphasis is given to the description of commonly used biopolymers - e.g. cellulose, chitin, and lignin - and their use in a variety of sample preparation strategies. We also refer to different functionalization approaches that enhance the extraction efficiency of natural sorbents.
人们对环境恶化和资源枯竭的日益关注，促使分析化学界开发出尽可能符合绿色分析化学原则的分析方法。通过缩小采样装置的尺寸和减少用于高效提取目标分子的吸附相的量，在绿色样品制备策略方面取得了重大进展。在这种情况下，使用天然吸附剂是绿色样品制备的另一种方便选择。使用天然吸附剂进行萃取的优点包括它们可从可再生资源中获得、低毒性和可生物降解性。在这篇综述中，我们描述了各种天然吸附剂在金属和有机分子萃取中的应用，重点介绍了 2009 年至 2019 年十年间最具创新性的应用。特别强调了常用生物聚合物（例如纤维素、甲壳素和木质素）的描述及其在各种样品制备策略中的应用。我们还提到了不同的功能化方法，这些方法可以提高天然吸附剂的萃取效率。
