Abstract: s Trace metals in oils are a kind of important factor of oils’ oxidization stability.To evaluate the quality of CTCBE and CB,trace metals(Cu、Fe、Co etc)from oils were determined by ICPMS,and their oxidization stability was compared by oven method.The results showed that most of these metals in CTCBE and CB were in low concentration,but active Cu、Fe、were in high concentration,especially in CB. However,CB’s stability was high,where as CTCBE was easily oxidized.
