【摘要】 采用活性炭纤维作电容去离子的电极,用于N aC l溶液的除盐实验,研究了电容去离子电极的性质.由实验结果可以看出,随着电极上所加电压的增加,电极上吸附容量随之增大,溶液中的离子浓度随之降低;当溶液种类和浓度一定时,吸附容量随着电压的增加而增加;当溶液种类和电压确定后,吸附容量随着浓度的增加而增加,并达到一个极限值.吸附还可以用Langm u ir吸附等温线来描述.更多还原

【Abstract】 Activated carbon fibers(ACF) were used to the electrodes of capacitive deionization(CDI) apparatus,adsorption of NaCl solution and character of CDI were studied.The results show that the adsorbed amount of ions on the ACF increases by applying an electric field.Adsorption of ions causes a decrease in the NaCl concentration of CDI apparatus.If the solution and the applied voltage are fixed,the adsorption amount of ions increases by increasing the concentration,then reaches a limited value.The adsorption of ions accords with Langmuir isotherms.更多还原
