摘要：
The As(V) adsorption onto bone char was investigated as a function of bone char dosage, pH and contact time in batch tests. The initial As(V) concentrations were varied from 0.1 to 1 mg/L to evaluate the adsorption kinetics and isotherm. The As(V) concentrations were analyzed using a graphite furnace atomic absorption spectrophotometer. The highest As(V) removal was found to be 62% after 3 d using 3 g bone char at a pH level of 4.0 for 0.5 mg/L As(V) concentration. The maximum adsorption capacity was 0.13 for 1 mg/L As(V) concentration. A Langmuir isotherm and second order adsorption kinetics were observed for As(V) adsorption.
