Abstract
The reactivity of hydroxylamine with HO2/O2- radicals was studied by pulse radiolysis and stopped-flow photolysis over a pH range of 1.1-10.5. Upper limits for the rate of reaction indicate that hydroxylamine, if it reacts at all, reacts at a very slow rate. Its use as an indicator for O-2 and an assay for superoxide dismutase is, therefore, inappropriate.
摘要
通过脉冲辐解和停流光解，在pH值为1.1至10.5的范围内研究了羟胺与HO₂/O₂⁻自由基的反应活性。反应速率的上限表明，羟胺即使发生反应，反应速率也非常缓慢。因此，将其用作O₂的指示剂和超氧化物歧化酶的测定方法是不合适的。
