随着工农业生产的迅速发展，水中硝酸盐氮污染已成为世界性的环境问题。水中含有硝酸盐会危害人们的健康。纳米铁具有粒径小，比表面积大，活性强的优点，能有效的去除水中硝酸盐，但是纳米Fe0系材料由于颗粒粒径小，极易团聚影响活性，需解决分散性问题；纳米Fe0系材料稳定性差，在环境中易氧化甚至自燃，需要苛刻的操作条件，处理污染物的反应在无氧的条件下才有较好的效果[1]。膨胀石墨负载纳米铁能有效去除纳米铁团聚的现象，同时能解决稳定性差的问题，增加去除硝酸盐的效果。本文采用液相还原法制备不同比例（质量比）的膨胀石墨与纳米铁复合材料，研究其去除不同浓度硝酸盐水的效果。实验结果表明，加入Fe:膨胀石墨=2.8:2的时候效果最佳，此比例下的复合材料去除60mg/L效果可以到50%以上，说明去除低浓度的硝酸盐水效果好。
用软件翻译的不行 这个我也会 太不准确了

With the rapid development of industrial and agricultural production, water nitrate-nitrogen pollution has become a worldwide environmental problems. Nitrates in the water are hazardous to people's health. Nano-iron with a small particle size, specific surface area, and the activity of the advantages of strong and effective removal of nitrate in the water, but the Department of nano-Fe0 materials of small particle size as a result, the impact of highly active reunion will take to resolve the issue of decentralization; nano Fe0 Department of Materials poor stability, oxidation in the environment or even spontaneous combustion, the need for harsh operating conditions, reflected in the treatment of the contaminated material under anaerobic conditions there can be a better effect [1]. Expanded graphite nano-iron load can effectively remove the phenomenon of nano-iron reunion, at the same time to solve the problem of poor stability and increase the effectiveness of nitrate removal.
