KINETIC STUDY ON SUPEROXIDE DISMUTASE ESTIMATED BY CHEMILUMINESCENCE METHOD

<正> Superoxide anion radicals （O2-） dismutate spontaneously into O2 and H2O2, but by the catalytic action of superoxide dismutase （SOD）, the reaction velocity increases by four or five orders of magnitude. As O2- has the property of instability, direct methods such as pulse radiolysis are frequendy used in the kinetic study of SOD, but they require expensive equi pments not suitable for general applications, so indirect methods have been investigated
