Can anybody suggest a suitable molecule to scavenge Dichlorine radical anion (Cl2.-). I am trying to figure out the involvement of Cl2.- in my system.
I don't know if there are some specific scavenging agents for chlorine radical. Please read our published papers. We found chlorine radicals attack phenol to form chlorinated phenol. Maybe it is a possible method to identify the involvement of these radicals. Please be cautious if other radicals coexist.
You can use sodium nitrite (NaNO2) as efficient scavenger. The rate constant for reaction between dichlorine radical and nitrite is very high (2.5 x 10^8 /M-s).
Thank you very much Zhaohui Wang and Alok D. Bokare. However, up to my knowledge, the rate constant of dichlorine radical reaction with my target molecule is 1.4 x 10^9 M-1s-1 (significantly faster than NaNO2-dichlorine radical reaction rate).
Use of excess sodium nitrite will compensate for the one order of magnitude decrease in rate constant. Higher concentration of sodium nitrite may not completely scavenge all dichlorine radicals but there will a substantial decrease in reactivity with your target molecule.
