In many literature they have mentioned EDTA, IPA and BQ but how much volume and concentration should be used to perform the radical scavenging tests?
Nashwa Fetyan
EDTA, benzoquinone, and isopropyl alcohol were used as scavengers introduced into the photocatalytic process to capture holes, superoxide radical (˙O2−), and hydroxyl radical (˙OH), respectively. The concentrations of the EDTA and benzoquinone were both 1 mmol L−1, and 0.1 mL isopropyl alcohol was added into 400 mL reaction solution (Liu et, 2019).
The compounds of n-butanol (n-BuOH, 0.5 M), benzoquinone (0.25 mM), and EDTA-2Na (0.01 M) were used as hydroxyl radicals (•OH), superoxide radicals (O2 •−), and hole (h+ ) scavengers, respectively (Zhang et al, 2019)
