石墨烯气凝胶吸附污水中重金属离子研究的自然辩证法评述
|
摘要
随着经济的高速发展,工业生产中的废水不加处理或处理不当排放到水体中导致水体中重金属离子含量偏高的现象屡有发生。因重金属离子毒性极高,不能生物降解且容易在动植物体内积累,从而会导致严重危害。因此,研究一种高效吸附污水中重金属离子的吸附剂意义重大。水热自组装和热退火工艺制备的具有三维网状多孔结构的石墨烯气凝胶具有高孔隙率,对重金属离子有良好的吸附能力,是去除污水中重金属离子的理想材料。本文运用自然辩证法的指导方法和理论,对石墨烯气凝胶的研发与应用进行了评述,分析不同吸附材料的性能及发展前景,以期更加快速有效地进行科学研究。
With the development of the economy, the waste water in industrial production is not treated or treated by improper discharge, which leads to the high content of heavy metal ions. Because of the high toxicity of heavy metal ions, it can not be biodegraded and easily accumulated in the animals and plants, which has become a serious pollution problem. Therefore, it is urgent to study an adsorbent for highly effective adsorption of heavy metal ions. The graphene aerogels, which are prepared by hydrothermal self-assembly and thermal annealing, have high porosity and adsorption capacity to heavy metal ions. They are ideal materials for removal of heavy metal ions. The practice of graphene based aerogels and their applications for adsorption of heavy metal ions was combined with the theory of natural dialectics to review the progress. It will provide reference for the development of adsorption materials for heavy metal ions, environment friendly and high economic benefits.
