固体材料对咸水中钠离子吸附效果研究

A Study on the Adsorbing Effect of Solid Materials to Na^+ Ions in Brackish Water

水资源短缺一直是影响工、农业阔步发展的主要因素。合理利用微咸水及咸水是解决现阶段工、农业用水短缺的重要举措。通过模拟试验,研究了不同浓度梯度的Na Cl盐水经材料处理后对盐基离子的吸附、脱附效果。研究结果表明,恒温震荡吸附后,盐水中Na+含量有所下降。综合效果最好的材料是活性炭类(YK、GK),吸附率最高达40.28%,对应脱附率为6.52%;其次是树脂类(H、HBYX),吸附率最高为32.96%,脱附率为9.61%。

Water shortage has been the main factor hindering the development of industry and agriculture. Rational utilization of brackish wa- ter and salt water is an important measure to resolve the current problem. Through simulation experiment, this paper studies the adsorption and desorption abilities of different materials for salt-base ions of NaC1 solution with different concentration. The results show that after con- cussion absorbing under the same temperature, the Na＋ content in brine is reduced. In general, the best materials are activated carbon （ YK, GK）, its absorbing rate is up to 40.28% and the corresponding desorption rate is 6.52%; the second are resin （H, HBYX）, its absorbing rate is as high as 32.96% and the desorption rate is 9.61%.
