摘　　要：将纳米碳管制成电极,研究端电压、氯化钠溶液流量、氯化钠溶液初始浓度、纳米碳管管径对纳米碳管电极电吸附氯化钠性能的影响,结果表明:纳米碳管电极最佳脱盐的端电压和氯化钠溶液流量分别为2.0V和10mL/min,并且纳米碳管电极脱盐与纳米碳管的比表面积和氯化钠溶液初始浓度有关,在大量的实验数据上,得出了电极脱盐方程为ηdesalt=KC01/4S2/5。Electrodes was fabricated by carbon nanotubes,the desalination characterization of electrodes by electric adsorption was studied,and the measurement and analysis at different conditions such as pore structure of carbon nanotubes,terminal voltage,NaCl solution current,starting NaCl solution concentration and number of electrode sheets were adopted.It was suggested that the best work condition was 2.0 V in terminal voltage and 10 mL/min in NaCl solution current,desalination of carbon nanotube electrodes had a relation with specific surface area of carbon nanotube and starting NaCl solution concentration and desalting the NaCl solution was 2～10nm.And equation ηdesalt=KC1/40S2/5 was getted for desalination by electrodes based on large experimental data.
