【摘要】 通过一步水热法制备石墨烯复合水凝胶,在自制的三维电极中催化处理苯酚废水,通过实验分析废水初始浓度、pH、电解电压、负载贵金属对苯酚去除效果的影响,并确定出最佳反应条件。实验结果证明三维电极催化氧化去除废水中苯酚这项工艺是可行的,且其最佳反应是条件为:pH控制在3左右,酸性也可行,电解电压在15V左右,电解时间为90min,并加以搅拌磁子的搅拌。更多还原

【Abstract】 By step hydrothermal preparation of graphene composite hydrogel, in homemade three-dimensional electrode catalytic treatment of phenol wastewater, through the experimental analysis of wastewater, initial concentration, p H, electrolytic voltage, load the effects of the precious metal on phenol removal and the best reaction conditions were determined. Experimental results show that the three-dimensional electrode catalytic oxidation of phenol in waste water to remove the technology is feasible, and the optimum reaction conditions for: the p H control in 3, acidity and feasible, the electrolysis voltage in 15 V, electrolytic time of 90 min, mixing and stirring magneton.更多还原
