Simultaneous Determination of Bismuth and Iron in Bismuth Concentrates by the EDTA Method

Determination conditions ,disturbance and elimination methods,precipitation recovery and so on for simultaneous determination of bismuth and iron in the bismuth concentrates by the EDTA method were studied. In the presence of massive bismuth ,the simultaneous determination method of bismuth and iron in the bismuth concentrates was established. this method was good applicability,simple operation,high accuracy.
