SOD could decompose O2•- into H2O2, and then CAT and APX could degrade H2O2 into H2O and O2 (Ge, Li, et al., 2019). This study found that HRW treatment enhanced the activity and gene expression of SOD and CAT during the entire storage period in R. sterilis fruit. Li, Hu, et ...
At pH 7, the oxidation potential of H2) is about -0.8. This means that to put in the potential that you need to oxidise Cl-, you will oxidise H2O to oxygen first. Try doing it in a solvent that is more resistant to oxidation.Grafter Logged ...
