高价值和低容量提取物的回收和分离对于零废物生物炼制的商业实现是一个相当大的挑战。基于可持续吸附剂的固相萃取是一种高效、绿色、选择性分离这些复杂萃取混合物的有效方法。由可再生多糖衍生的介孔碳质固体由于其可调节的功能性和表面结构而成为理想的固定相。在这项研究中，13个多糖衍生的介孔材料和两个改性类型作为吸附剂的10个天然存在的生物活性酚类化合物的结构-分离关系进行了研究。第一次，进行了全面的统计分析的关键分子和表面特性影响这些物种的恢复。所获得的结果表明，开发定制的材料的纯化，分离或提取，根据分析物的分子组成的可能性。这些多糖衍生的介孔材料的广泛通用性和应用范围为传统的二氧化硅基固定相提供了新的可持续和廉价的替代品。
The recovery and separation of high value and low volume extractives are a considerable challenge for the commercial realisation of zero-waste biorefineries. Using solid-phase extractions (SPE) based on sustainable sorbents is a promising method to enable efficient, green and selective separation of these complex extractive mixtures. Mesoporous carbonaceous solids derived from renewable polysaccharides are ideal stationary phases due to their tuneable functionality and surface structure. In this study, the structure-separation relationships of thirteen polysaccharide-derived mesoporous materials and two modified types as sorbents for ten naturally-occurring bioactive phenolic compounds were investigated. For the first time, a comprehensive statistical analysis of the key molecular and surface properties influencing the recovery of these species was carried out. The obtained results show the possibility of developing tailored materials for purification, separation or extraction, depending on the molecular composition of the analyte. The wide versatility and application span of these polysaccharide-derived mesoporous materials offer new sustainable and inexpensive alternatives to traditional silica-based stationary phases.
