中文摘要： 青海盐湖氯化镁资源非常丰富，但是其综合利用水平低。大力发展镁基环保产品，发挥盐湖氯化镁资源品质高、开采成本低的优势，不仅能够提高盐湖氯化镁资源大规模开发，促进青海区域经济发展，更能为全国环境治理工作供应充足绿色安全处理剂，提供物资保障。在此项目中，我们提出通过有机功能修饰，构筑不同交联模式的新型镁基层状化合物复合水凝胶材料。深入系统开展其在吸附净化烟气中的SO2和NOx的应用，从分子水平上探索复合水凝胶体系与吸收气体分子形成的稳定和不稳定的复杂结构，揭示构效关系，实现功能强化。发展复合水凝胶材料的宏量制备工艺，解决吸附、解吸过程中的废液分离和凝胶再生等难题，实现过程强化。通过本项目的研究，为规模化利用青海盐湖镁资源和推动青海区域经济发展提供重要的途径。预期发表8篇以上高水平SCI论文，申请4项以上国家发明专利，培养博士和硕士研究生4-7名。

英文摘要： The magnesium chloride resources in Qinghai are very rich, but its utilization is quite poor. Since the magnesium chloride resources in Qinghai have high quality and low cost, the development of magnesium-based environmental protection agents can not only improve the large-scale utilization of the salt lake magnesium chloride resources, but also promote the regional economic development in Qinghai. At the same time, such utilization can also provide plentiful green security agents for the national environmental governance. In this project, we propose to develop new magnesium-based layered composite hydrogel materials to conduct in-depth study on their application in the absorb SO2 and NOx from fuel gas; to have a better understanding of the structural design of the magnesium-based layered compounds composite hydrogel; to strengthen the functionality process; to develop the macro preparation technology of the composite hydrogel materials and to solve the waste liquid separation and gel regeneration process for the adsorption and desorption, and to strengthen the implementation process. This project can provide important pathway for highly efficient use of the magnesium resources in Qinghai, improve the production and living environment and its local economy development. We expect to publish more than 8 SCI papers with high quality, to apply more than four national invention patents, and to educate 4-7 doctoral and postgraduate candidates.
