采用本组自行改进的NBT（氮蓝四唑）光照法对PH=7.8的磷酸盐缓冲夜体系中一水合甘氨酰甘氨酸铜Cu（Gly-Gly）·Ho催化超氧阴离子自由基O·_（2）~（-）歧化反应进行了研究,求得不同温度下的催化反应速率常数Kcat、反应级数n、活化能Ea及指前因子A。同时,研究结果进一步表明:经我们改进后的光照法,在测量精度方面确有很大改观,并可进行不同温度下的测定,显示出其独特的优越性。
Using this group of self-improving NBT (nitrogen blue tetrazolium) light irradiation of PH = 7.8 phosphate buffered night system glycylglycine monohydrate Cu (Gly-Gly) · Ho catalytic superoxide anion radical O · _ (2) ~ (-) disproportionation reaction were studied, and the catalytic reaction rate constant Kcat, reaction order n, activation energy Ea and pre-exponential factor A were obtained under different temperatures. At the same time, the research results further show that: our improved light method has great improvement in measuring accuracy, and can be measured at different temperatures, showing its unique superiority.
