英文摘要	In this work, the Fe-Si-B amorphous alloy ribbons were successfully prepared by melt-spinning technique and compared with commercial 300 mesh iron powders for Cu() removal efficiency. The results show that Fe-Si-B amorphous alloy ribbons were efficient in removing Cu() from aqueous solution containing 100 mg/L of Cu(), where more than 98% of Cu() was removed within 60 min using 1 g/L Fe-Si-B amorphous alloy ribbons, and the removal process can be described by a pseudo-first-order kinetic model. Under the same conditions, the surface normalized reaction rate constants for the removal of Cu() by Fe-Si-B amorphous alloy ribbons is 167 times than that of 300 mesh iron powders. And the removal rate is proportional to solution pH and temperature, but inversely proportional to Cu() concentration. In addition, it was found that the ribbons still exhibited 67% removal efficiency after six repeated uses. © 2020, Materials Review Magazine. All right reserved.
