· CCl 3 radicals formed in the first step of the CCl 4 degradation react with iron powder to form an intermediate with an Fe–C σ bond. In the absence of iron powder, · CCl 3 radicals formed by γ‐irradiation react with 2‐propanol in a chain reaction toward dechlorination. When the irradiated solution contains iron powder, the iron scavenges the · CCl 3 radicals, thus inhibiting the chain reaction. The minor product of the dechlorination of CCl 4 by iron powder in aqueous solution is CH 4 , contrary to the results reported in the literature for the electrochemical reduction of CCl 4 on iron electrodes.
