摘　　要：用双驱动动态膜压仪研究腐殖酸在天然水体气 -液界面的物理化学行为 ,通过气 -液界面膜的研究发现腐殖酸富集在气 -液界面 ,存在着表面超量 ,其表面超量与水体中腐殖酸的含量有关 ,利用这个方法有望简化水体中腐殖酸含量的测定方法。The instrument of double-drive dynamic film p ressure balance was used to study the behavior of humic acid in air-liquid inte rface. Research of surface film in air-liquid interface shows that humic acid tends to be enriched in air-liquid interface and has the characteristic of surface excess.Surface excess has a direct relationship with concentration of h umic acid solution,which indicates that the method may be used to simplify deter mining the content of humic acid in water.
