Researches on the desulphurization with white mud The existing utilization of the white mud has multiple ways, such as making cement, bricks and other building materials, padding materials for the road and factory foundation, improving agricultural acid soils, the deep development of fine chemical products, etc.
These are certain limitations for all these usages, such as some compositions in the white mud make the quality of building materials difficult to have long-term stability, the weathering and soluble white mud will decrease the bearing capacity of the foundation, not enough deep research makes the promotion blocked for soil improvement, the high cost makes the development of fine chemical products limited.
His current research interests include the security, environmental and economic operation of thermal power plant Gao Wei, He is currently a professor in the school of Energy and Power Engineering, Huazhong University of Science & Technology.

Adsorption is one of the efficient methods in humic acid removal.Many solid materials as adsorbents have been investigated, which include activated carbons, natural and synthetic zeolites, clays and modified clay minerals, alumina, resins, chitosan, fly ash, aminated polyacrylonitrile fibers and Mg/Al layered double hydroxides[4-7].Moreover, Cucurbiturils are one kind of new functional materials compounds which possess a hydrophobic cavity accessible through portals surrounded by polar carbonyl groups capable of including a variety of hydrophobic and the appearance of hydrophilic[8].
In this work, a new functional materials compounds of Cucurbiturilss was first used for the removal of HA from aqueous solutions which separately from amount of adsorbent , initial HA concentration, pH values and competitive anions.The proposed method had been applied to remove humic acid in wastewater with satisfactory results.
