通过与阳离子表面活性剂形成离子对的方法分离黄腐酸

Separation of fulvic acid through ion-pair formation with cationic surfactant

使用较大分子量的阳离子表面活性剂作为黄腐酸(FA)的对离子,考察了离子对沉淀形成的最佳条件及精制方法,并对被分离了的黄腐酸的化学组成进行了讨论。

Cation surfactant with large molecular was usedas the counterion of fulvic acid to form ion pair. The con-ditions and extraction approaches of the precipitation wereinvestigated. The chemical composition of the extractedfulvic acid was also analyzed.
