摘要：

In this work, attapulgite was modified by acidification, organic pretreatment and load the tannin acid on the attapulgite by formaldehyde, respectively. Then PVDF/modified attapulgite composite membrane was prepared by the method of phase inversion. The structure and morphology of the modified attapulgite was characterized by Fourier transform infrared and transmission electron microscope, and the adsorption of Ni(II) was studied by the method of ultraviolet absorption. The results showed that composite membrane filled with the tannic acid-modified attapulgite could remove the Ni(II) in the aqueous solution effectively, and the absorption increased by 34% than the membrane filled with pure attapulgite modified.
