摘要：
Phosphorus removal capacities (PRCs) of basic oxygen furnace slag (BOF-slag) in different pH ranges were investigated using batch experiments. The fractions of different phosphorus containing compounds in fresh and reacted BOF-slag were measured by chemical extraction methods. Fresh and reacted BOF-slag was characterized through combining several methods. The results show that BOF-slag had high PRCs (21-30 mg P/g) and that the PRCs of BOF-slag at alkaline pH were comparable to the ones at neutral and acidic pH. At alkaline pH, phosphorus removal occurred via both the weak adsorption onto BOF-slag and the precipitation of calcium phosphates. At neutral and acidic pH, phosphorus removal was achieved through the chemical adsorption onto Fe containing minerals in BOF-slag. Influences of the pH on weakly bound phosphorus, Ca associated phosphorus, and Fe associated phosphorus in the reacted BOF-slag were also discussed in detail. (C) 2016 Elsevier B.V.
