摘要
腐植酸是一类具有代表性的功能型天然高分子化合物,其商业价值较高,发展前景良好.但天然腐植酸的形成需要很长时间,因此采用人工方法合成腐植酸被认为是一种优秀的增值方法.本文综述了腐植酸的结构性质、来源、制备与应用方面的研究进展.首先,介绍了腐植酸的结构性质和功能;接着按照来源将腐植酸分为矿源腐植酸和生物腐植酸两类;然后阐述了微生物分解法、水热法、催化/氧化法和热解法四种增强腐植酸制备方法的研究现状,并进一步介绍了腐植酸在农业、工业、医药、环保和新型材料领域的应用情况;最后还根据腐植酸在增强制备和应用方面存在的挑战,进行了展望.
Humic acid is a representative class of functional natural polymer compound with high commercial value and good development prospects.However,the formation of natural humic acid takes a long time,so the synthesis of humic acid by the artificial methods is considered to be an excellent value-added method.This study reviews the research progress in structural properties,sources,preparation and applications of humic acids.Firstly,we introduce the structural properties and function of humic acids;and then by classifing it into two categories according to their sources:mineral humic acids and biological humic acids,we describe the current research status of four enhanced humic acid preparation methods:microbial decomposition,hydrothermal method,catalytic/oxidation method and pyrolysis method,as well as the applications of humic acids in agriculture,industry,medicine,environmental protection and new materials.Finally,we give a outlook according to the challenges in the enhanced preparation and applications of humic acids.
