Abstract: The influences of the components of Mn-Sn-Ce/GAC particle electrode load liquid on the electrochemical treatment capability for 4-chlorophenol simulated wastewater have been investigated. The composition of Mn-Sn-Ce/GAC particle electrode load liquid has been optimized by the response surface method. The optimal ratio is that SnCl₄·5H₂O is 50 g/L, CeCl₃·7H₂O 3.7 g/L,and Mn(NO₃)₂ 25 g/L. The prepared Mn-Sn-Ce/GAC particle electrodes are used for the treatment of 200 mL of 4-chlorophenol wastewater(its mass concentration is 200 mg/L). Under the following conditions:the concentration of Na₂SO₄ is 0.05 mol/L,plate spacing 3 cm,current 1 A,Mn-Sn-Ce/GAC particle electrode dosage 10.0 g,and electrolysis time 15 min,the removing rate of 4-chlorophenol is 98.97%.
