Under the guide of chemical bonding, a composite membrane had been fabricated successfully through grafting of a coordination complex modified polyoxometalate to an ethylenediamine planted polyvinylidene fluoride. Compared with neat polyvinylidene fluoride membrane, the oxytetracycline adsorption capacity of the polyoxometalate grafted composite membrane has been improved to a great extent. In addition, this polyoxometalate grafted composite membrane also exhibits excellent hydrophilicity, which leads to a clear enhancement in its antifouling properties. Besides oxytetracycline, its performances in the removal of other tetracycline‐type antibiotics, such as tetracycline and doxycycline, also looks outstanding. Furthermore, after successive adsorption and desorption experiments, the pollutant removal activity and antifouling property of this composite membrane are well retained, which suggests it is stable for removing tetracycline‐type antibiotics in waste water treatment processes.
