| Abstract: |
| Electrochemical method was used to remove thiocyanate. The results show that the removal rate of thiocyanate is 80.2% under the condition of current density of 40 A·m?2, initial thiocyanate concentration of 3.45 mmol·L?1, pH 3 and 2 h. The main products of the reaction are SO42? and CN?. The limiting step and reaction order are different under different current density. pH value has no significant effect on the degradation of thiocyanate. Fe2+ and Cl? have negative effects on the electrochemical degradation of thiocyanate. |
