Study on Effect of Trace Metals to the Oxidant Stability of CTCBE(Ⅱ)

Abstract

Abstract: Tracemetals inoils areanimportant factorofoils’ oxidizationstability.Toevaluate theeffectoftracemetals(Cu?Fe?Coetc)to the quality of CTCBE,trace metals were determinedby ICP -MS,and several antioxidant effects were compared with oven method.The r esults showed that most of these meta ls in CTCBEwere lowconcentration,b ut active Cu?Fe were of highconcentration.CTCBE was easily oxidized.Metal combination Na 2 (EDTA)and lemon acid could defer oxidation,andthey hadbetter effect if composed of antioxid ant.

Key words: Trace metals , CTCBE , Antioxidant , Oxid ization stability
