摘要：Electrochemical oxidation process is a promising treatment technology for the
degradation of organic pollutants in water samples. Few studies demonstrated that the
electrochemical oxidation process plays a key role on the removal of NH3 from leachate.
The removal efficiency of NH3 increases with applied voltage very significantly,
suggesting a very important role of mediated oxidation process. Furthermore, pH and
electrolyte are also participated strongly to enhance the removal of NH3 in leachate. To
optimize the operating conditions, the effects of NaCl concentration, applied voltage, and
pH of the solution were investigated statisticall by one-way ANOVA; all factors were
found as a significant factor with ! = 0.05 lower than 95% confidence level. However, the
consumption energy was considered during electrochemical oxidation process. In chloride
media, consumption energy is the lowest (33 kW h mg−1
), at 0.086 mol L−1 NaCl and 10
V, with high removal percentage of NH3 which is 48%. In case of applied voltage, only
53% of NH3 has been removed consuming more than 50 kW h mg−1 after 105 min at
0.043 mol L−1 NaCl and 20 V. All results are treated statistically by applying one-way
ANOVA, interval confidence 95% and P-value 0.05.
