Abstract: The relation between the content of the cofactor Cu2+of bovine superoxide dismustase and enzyme's activity is studied.Different amount of Cu2+is added into SOD solution,then Cu2+in SOD reaches new distribution balance.The content of free Cu2+is determined by GFAAS after preconcentration on Nafion modified tungsten coil,and the enzyme's activity is detected by the method of 1,2,3-trihydroxybenzene auto-oxidation.

Key words: Superoxide dismutase, Copper, Enzyme's activity
