In order to investigate the degradation dynamics of rhodamine B in electric fenton, reaction kinetics were studied in different initial pH value, temperature, concentration of Fe2+.Results showed that when the solution pH were 1,3,4 and 7, the reaction rate con-stants were 0.032 7, 0.033 9, 0.020 3 and 0.014 9 min-1 , respectively.When the solu-tion temperature were 10, 20 and 30 ℃, the reaction rate constants were 0.0317, 0.0339 and 0 .0351 min-1 .When the concentration of ferrous were 7 , 10 , 15 and 20 mmol/L, the reaction rate constants were 0.021 4, 0.032 7, 0.033 8 and 0.0407 min-1 , respectively. Overall, the degradation followed the first-order reaction.
