摘要
研究了Mn-Sn-Ce/GAC粒子电极负载液组成对4-氯酚模拟废水电化学处理效果的影响。通过响应面法优化了Mn-Sn-Ce/GAC粒子电极负载液的组成,最优配比为SnCl_4·5H_2O 50 g/L、CeCl_3·7H_2O 3.7 g/L、Mn(NO_3)_2 25 g/L。以最优配比制备的Mn-Sn-Ce/GAC粒子电极处理200 mL 200 mg/L的4-氯酚废水,在电解质Na_2SO_4为0.05 mol/L、板间距为3 cm、电流为1 A、Mn-Sn-Ce/GAC为10.0 g、电解15 min条件下,4-氯酚去除率达98.97%。
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%.
