| 摘 要： | 将改性的LSX分子筛按一定比例掺加到活性炭中,制成复合电极(CE),测定了其在不同的吸附时间、分子筛含量、电压、电极间距、电极片质量下,该复合电极对钙离子的去除率。同时比较了其与普通活性炭电极(AC)对钙离子的吸附能力。结果表明,在Ca2+/Na+溶液中,钙离子吸附量提高了1.08倍,在Ca2+/Mg2+溶液中,钙离子吸附量提高了0.6倍,在Ca2+/K+溶液中,吸附量提高了7.45倍,在海水溶液中,吸附量提高了2倍。

| Abstract: | Adding a certain proportion modified molecular sieve to the activated carbon to make composite electrodes,the elimination ratio for calcium ion of the composite electrodes were measured under different adsorption time,molecular sieve content,voltage,distance between the electrodes and weight of the electrodes.At the same time,the adsorptive capacity of calcium ion between composite electrodes and the common activated carbon electrodes were compared.The results showed that in the solution of Ca2+/Na+,the adsorption of calcium ion increased by 1.08 times.In the solution of Ca2+/Mg2+ and Ca2+/ K+,the adsorption capacity of calcium ion increased by 0.6 and 7.45 times.In the seawater,the adsorptive capacity increased by 2 times. |
