| Abstract: | In order to investigate the degradation dynamics of rhodamine B in electric fenton,reaction kinetics were studied in different initial p H value,temperature,concentration of Fe^2＋. Results showed that when the solution p H were 1,3,4 and 7,the reaction rate constants were 0. 032 7,0. 033 9,0. 020 3 and 0. 014 9 min^-1,respectively. When the solution 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. |
