TI  - A high activity of Ti/SnO2-Sb electrode in the electrochemical degradation of 
      2,4-dichlorophenol in aqueous solution.
PG  - 1424-30
AB  - Electrochemical degradation of 2,4-dichlorophenol (2,4-DCP) in aqueous solution 
      was investigated over Ti/SnO2-Sb anode. The factors influencing the degradation 
      rate, such as applied current density (2-40 mA/cm2), pH (3-11) and initial 
      concentration (5-200 mg/L) were evaluated. The degradation of 2,4-DCP followed 
      apparent pseudo first-order kinetics. The degradation ratio on Ti/SnO2-Sb anode 
      attained > 99.9% after 20 min of electrolysis at initial 5-200 mg/L 
      concentrations at a constant current density of 30 mA/cm2 with a 10 mmol/L sodium 
      sulphate (Na2SO4) supporting electrolyte solution. The results showed that 
      2,4-DCP (100 mg/L) degradation and total organic carbon (TOC) removal ratio 
      achieved 99.9% and 92.8%, respectively, at the optimal conditions after 30 min 
      electrolysis. Under this condition, the degradation rate constant (k) and the 
      degradation half-life (t1/2) were 0.21 min- and (2.8 +/- 0.2) min, respectively. 
      Mainly carboxylic acids (propanoic acid, maleic acid, propanedioic acid, acetic 
      acid and oxalic acid) were detected as intermediates. The energy efficiencies for 
      2,4-DCP degradation (5-200 mg/L) with Ti/SnO2-Sb anode ranged from 0.672 to 1.602 
      g/kWh. The Ti/SnO2-Sb anode with a high activity to rapid organic oxidation could 
      be employed to degrade chlorophenols, particularly 2,4-DCP in wastewater.
