Abstract

The development of carbon-based adsorbents for flavonoid purification has gained significant attention due to their high efficiency, sustainability, and cost-effectiveness. Derived from agricultural waste, such as fruit peels, husks, and stems, bio-adsorbents offer an eco-friendly approach to valorizing biomass. These materials are rich in carbon content and can be transformed into highly porous activated carbon through pyrolysis and chemical activation. Chemical activation methods, employing agents like phosphoric acid, zinc chloride, or potassium hydroxide, enhance the surface area, pore volume, and functional groups of the adsorbent, optimizing its adsorption capacity. Advanced carbon-based adsorption techniques leverage these properties to selectively bind flavonoids, benefiting from the high specificity and stability of the adsorbent. Adsorption mechanisms, including hydrogen bonding and van der Waals forces, play a crucial role in the effective capture of flavonoids. These processes are influenced by factors, such as surface chemistry, pore structure, and adsorbate properties, making carbon-based adsorbents a versatile and sustainable solution for purifying valuable bioactive compounds in pharmaceutical and nutraceutical industries.

将商品作物副产品转化为碳基吸附剂用于类黄酮的回收：关键热解参数、化学活化和吸附机理综述

碳基类黄酮吸附剂因其高效、可持续性和高性价比而受到广泛关注。生物吸附剂来源于农业废弃物，如果皮、果皮和茎干，它提供了一种生态友好的方法来实现生物质的增值。这些材料含碳量丰富，可以通过热解和化学活化转化为高多孔活性炭。化学活化方法采用磷酸、氯化锌或氢氧化钾等试剂，增强吸附剂的表面积、孔隙体积和官能团，优化其吸附能力。先进的碳基吸附技术利用这些特性选择性地结合黄酮类化合物，受益于吸附剂的高特异性和稳定性。吸附机制，包括氢键和范德华力，在类黄酮的有效捕获中起着至关重要的作用。这些过程受表面化学、孔隙结构和吸附质性质等因素的影响，使碳基吸附剂成为制药和营养保健行业中净化有价值的生物活性化合物的通用和可持续的解决方案。

期刊介绍： The Journal of Separation Science (JSS) is the most comprehensive source in separation science, since it covers all areas of chromatographic and electrophoretic separation methods in theory and practice, both in the analytical and in the preparative mode, solid phase extraction, sample preparation, and related techniques. Manuscripts on methodological or instrumental developments, including detection aspects, in particular mass spectrometry, as well as on innovative applications will also be published. Manuscripts on hyphenation, automation, and miniaturization are particularly welcome. Pre- and post-separation facets of a total analysis may be covered as well as the underlying logic of the development or application of a method.
