Using Ti-bearing blast furnace slag as the adsorbent for total phosphorus removal from waste water,the performances and mechanisms for total phosphorus adsorption of the slag were studied by combination of the kinetics equation and isothermal adsorption equation. The results show that the adsorption of total phosphorus by Ti-bearing blast furnace slag is consisted of surface adsorption and particle inner diffusion stages,and the process is more inclined to monolayer chemical adsorption.96% of total phosphorus in 100 mL(50 mg·L-1 of KH2PO4 concentration) solution can be removed by 6.0 g Ti-bearing blast furnace slag with 40 ~60 mesh of particle size,at 20 ℃ for 60 min and p H = 8.
