From the viewpoint of the removal of tramp element, the thermodynamic properties of arsenic in molten Fe-C alloy was investigated between 1523K to 1823K by using chemical equilibrating technique. The effects of the arsenic, carbon concentration and the temperature on the activity coefficient of arsenic were also measured. The activity coefficient of arsenic in carbon saturated iron was measured as 0.09 at 1673K. The following activity coefficient of arsenic in molten iron was derived in terms of interaction parameters and temperature. □ By combining the present experimental results and the reference for thermodynamic properties of arsenic, the possibility of the removal of arsenic from molten iron by evaporation was discussed.
