Abstract In this work, Cu-Zn alloy powder and α-Al₂O₃ powder were blended to prepare Cu-Zn/α-Al₂O₃ hollow fiber membrane using phase transformation sintering technique. Sintering temperature was 1 300 ℃. Cross-section and outer surface of the hollow fiber membrane were studied using electron scanning microscope (SEM). The effect of Cu-Zn alloy content on membrane properties and Cu-Zn/α-Al₂O₃ hollow fiber membrane's anti-bacteria properties were studied. Results show that average pore size range of Cu-Zn/α-Al₂O₃ hollow fiber membrane is 0.314—0.438 μm. The optimal Cu-Zn alloy content is 3% (mass fraction), at which content pure water flux is 2 462.11 L/ (m²·h), bending strength is 8.11 MPa, bacteria reduction rate is 99.99%, bacteria inhibition rate is 73.1%.

Key words： phase transformation Cu-Zn alloy hollow fiber membrane antimicrobial
