%X The efficiencies of Skeletonema costatum removal were influenced by different clays. We studied the relationships between removal efficiencies (RE) and the features of different clays. Our results showed that, for different clays at 0.50g/L, the Zeta potentials of ranged from ?36.1 to ?15.9mV, the BET (Brunauer-Emmett-Teller) surface areas varied from 0.31 to 60.76 m2/g, the Si/Al ratios changes from 1.35 to 3.62, and the RE span from 13% to 82%. There were strong linear relationships between RE and Zeta potential, BET surface area, Si/Al ratio. High Zeta potential, BET surface area and low Si/Al ratio resulted in RE increasing. According to grey correlation analysis, BET surface area had the most significant effect on RE with a correlative degree of 0.907, while Si/Al ratio had the least effect on RE with a correlative degree of 0.618.
