固体材料对咸水中钠离子吸附效果研究

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%。

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

Water shortage has been the main factor hindering the development of industry and agriculture.Rational utilization of brackish water 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 NaCl solution with different concentration.The results show that after concussion 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％.
