高庙子膨润土与北山地下水的长期作用试验
|
摘要
以内蒙古兴和县高庙子钠基膨润土和甘肃北山BS05号钻孔地下水为研究对象,依托低氧手套箱,在常温低氧条件下开展膨润土与地下水长期作用试验研究,获得了1年内膨润土-北山地下水体系pH和Eh值随时间的变化特征;得到了作用前后体系液相关键离子成分以及固相可交换阳离子、化学成分,依托拉曼光谱仪测定了作用前后膨润土的结构。结果表明,膨润土-北山地下水体系在本试验条件和时间范围内可以保持相对稳定的状态。
In this paper, interaction between GMZ Na-bentonite sampled from Xinghe county, Inner Mongolia and Beishan BS05 groundwater of Gansu Province was carried out in glove box under ambient temperature and low-oxygen whose concentration was less than 0.005‰ condition for about 1 year. The variation characteristics of pH and Eh of bentonite-groundwater system with time were investigated. The concentrations of key cations in liquid were obtained. Chemical composition, exchangeable cations and chemical composition of bentonite after reaction were determined. At mean time, the structure of bentonite was analysised using Raman spectrometer. The results show that bentonite-groundwater system can maintain a relatively stable state in experimental condition and time range.
