In this paper, the ζ-pH curve of Zhejiang reflux diatomite, Jiling reflux diatomite and the Jiling reflux diatomite modified by organic amine, polyethylene, organocationic ions, organofunction group and metallic ion was studied, its isoelectrical point (IEP) was determined. The results showed: the surface properties of diatomite varied after modified; the reason for variation was concerned with different organofunction group and metallic ion. The relationship between the amount of adsorption of urokinase and IEP was also studied. The capacity of adsorption also varied with IEP value, after diatomite was modified.
