摘要
氧化石墨烯(GO)具有广阔应用前景,随着其生产和使用量的不断增大,GO不可避免地会进入到环境中而产生环境风险。GO在环境介质上的吸附聚集行为对于评价GO的环境风险具有重要的科学意义。通过宏观静态吸附实验研究了GO在环境介质(Al_2O_3、SiO_2、LDH等)上的吸附聚集行为,并详细研究了不同环境条件对其吸附聚集的影响规律。结合微观结构表征及理论计算模拟阐明GO与环境介质的相互作用机理。
A broad perspective can be seen for the application of graphene oxide(GO).However,due to its expanding production and practical applications,it will be unavoidable for its entrance into environment and bring the environmental risks.The adsorption and aggregation behaviors of GO in environmental media has a significant scientific meaning in evaluating its potential environmental risks.We investigated the adsorption/aggregation behaviors of different types GOs on different environmental media(Al_2O_3、SiO_2、LDH) by batch adsorption experiments.The adsorption/aggregation mechanism was elucidated by microstructure characterization and computational simulations.
