Application of nano-graphene oxide in heavy metal absorption:
Graphene oxide has a relatively large surface area, and the abundant oxygen-containing functional groups on its surface make it have good hydrophilicity and can be stably dispersed in aqueous solution, which is a potential high-quality adsorbent. Existing studies have shown that the treatment effect of graphene oxide on heavy metal and cationic dye wastewater is significantly better than that of widely used traditional adsorbents.
High adsorption performance:
Due to its special structure and high specific surface area, nano-graphene oxide can provide more adsorption sites and effectively adsorb heavy metal ions. Studies have shown that nano-graphene oxide has a high adsorption capacity and adsorption speed for a variety of heavy metal ions (such as lead, cadmium, mercury, etc.). Therefore, nano-graphene oxide can be used as a highly efficient adsorbent in heavy metal removal and wastewater treatment.
Renewable:
Nano-graphene oxide also has good reproducibility, by adjusting the adsorption conditions (such as temperature, solution pH value, etc.), it can achieve the de-echo regeneration of heavy metals by nano-graphene oxide. This reproducibility allows nano-graphene oxide to have a longer service life and lower cost in practical applications.
Environmental friendliness:
Nano graphene oxide has excellent environmental friendliness and does not produce secondary pollution. Compared with traditional adsorbents, nano-graphene oxide does not need to add a large number of chemical reagents, is non-toxic and harmless, and is easy to handle and recycle. Therefore, nano-graphene oxide has great potential in environmental protection and resource recovery.
