Abstract

Abstract: At present, most of clay minerals was negatively charged, which need to be modified to improve the ability of remove algae. However, the modified material was not widely used to remove algae because of its high cost and secondary pollution. Algae removal was explored by the clay minerals with positively charged. Mg/Al hydrotalcite(Mg/Al-LDH) and Zn/Al hydrotalcite(Zn/Al-LDH) were synthesized by co-precipitation method and its calcination products (Mg/Al-LDO, Zn/Al-LDO) were prepared by heating Mg/Al-LDH and Zn/Al-LDO at 400 ℃; To know the practical applicability, a detailed removal study of Microcystis aeruginosa was carried out. The influences of different Mg/Al molar ratio, Zn/Al molar ratio, initial Microcystis aeruginosa concentration were investigated, and environmental friendliness of hydrotalcite were discussed. The results indicate that the best molar ratio of n_Mg∶n_Al(n_Zn∶n_Al) was 3∶1, and the removal capacity of Microcystis aeruginosa with Mg/Al-LDO was superior to Zn/Al-LDO. At this initial concentration of Microcystis aeruginosa rang, Mg/Al-LDO had a clear role in the removal of Microcystis aeruginosa. In addition, Mg/Al-LDO would not cause secondary pollution in stead, it has good environmental friendliness.

Key words: hydrotalcite, Microcystis aeruginosa, adsorption, environmental friendliness
