腐殖酸的提取、研究及应用进展简析

A Brife Review of Research and Application of Humic Acid

腐殖酸(HA)是腐殖质(HS)中一类不溶于酸性介质的大分子有机物,在土壤、自然水体中广泛存在。本文综述了关于典型HA提取方法优化及HA在农业、环保、医用及其他领域的典型研究及应用。HA组分的复杂、提取方法的优化应该紧密结合HA提取应用场景。根据不同提取来源及工艺获得的HA产品与其他材料结合使用,可拓展HA在不同领域中的应用。

Humic acid(HA)is a general term for a type of macromolecular organic compounds in humus(HS)that is insoluble in acidic media and widely exists in soil and natural water bodies.This article reviewed the optimization of typical HA extraction methods and the typical research and applications of HA in agriculture,environmental protection,medicine,and other fi elds.The optimization of extraction methods of HAshould be closely combined with the application scenarios due to the complexity of components.Combined with other materials,HA products obtained via different extraction sources and processes can be applied in an wilder range of fi elds.
