  • Iron-carbon microelectrolysis was employed to degrade two synthetic compounds sulfamethoxazole and carbamazepine. The effects of iron carbon mass ratio, reaction time, pH, iron dosing quantity and other factors on the degradation rate of sulfamethoxazole and carbamazepine were investigated. The results showed that sulfamethoxazole was completely removed within 60 minutes when pH=1,Fe:C=1:1,Fe=80 g·L-1. The highest degradation efficiency of carbamazepine (90%) occurred at 60 minutes with pH=1, Fe:C=1:4,Fe=80 g·L-1. Sulfamethoxazole and carbamazepine undergone redox reactions and the nitrogen was reduced to ammonia nitrogen. The degradation of sulfamethoxazole and carbamazepine was in accordance with pseudo first order reaction kinetics.
