摘要：

Sodium alginate / graphene oxide/ gallic acid (SA/GO/GA) complex gel beads were prepared and were characterized. Removal efficiency of algae onto SA/GO/GA complex gel beads were investigated with different GO and GA content. The results showed that the removal efficiency of algae from aqueous solutions using SA gel beads were very low, but introduction of GO and GA of complex gel beads could sharply increase the removal efficiency of algae onto by 3 times. The amounts of SA/ GO/GA complex gel beads have significant effect on removal of algae. In addition, for the density algae in the range of 2.17-17.36 cells/mL, there was a linear relation between the removal efficiency of algae and the density algae. This stoichiometric linear relation has directed significance to engineering application in eutrophic waters.
