This study focused on the removal of nitrate via the capacitive deionization using carbon aerogel electrodes. The influences of voltages and initial nitrate concentrations on the removal of nitrate and speciation of nitrogen are investigated. The results showed that the removal amount of nitrate increases from 2.30 mg/g to 5.18 mg/g when the applied voltage increased from 0.8 V to 1.2 V with the initial nitrate concentration of 100 ppm. These removal of nitrate may be contributed from the capacitance adsorption and the reduction of nitrate. The amount of nitrate removed by capacitance adsorption increased from 0.43 mg/g to 4.58 mg/g when the applied voltage increased from 0.8V to 1.2 V. At the meantime, the reduction and desorption nitrate did not affected by applying different voltage. The amount of nitrate removed by capacitance adsorption increased from 1.34 mg/g to 4.48 mg/g when the nitrate concentration increased from 10 ppm to 200 ppm, but decreased to 2.62 mg/g when nitrate concentration increased to 500 ppm. At low nitrate concentration (10 ppm), the removal efficiency reached 50.53%. And the capacitive adsorption ability was about 90.9% after four cycles. Ching-Ju Chin 秦靜如 2015 學位論文 ; thesis 84 zh-TW |
