Microstructure and Photocatalytic Decomposition of Methylene Blue by TiO2-Mounted Halloysite, a Natural Tubular Mineral

On the basis of analysis of structure and properties, halloysite, a natural tubular mineral, was developed for an environmental treatment. TiO2 was mounted into halloysite by using hydrolysis of tetrabutyl titanate at room temperature. The adsorption and photocatalytic performance of halloysite and TiO2-mounted halloysite have been examined in methylene blue aqueous solution in the dark and under ultraviolet ray irradiation, respectively. Their performance of adsorption and photodecomposition was evaluated from the adsorbed and degraded amounts of methylene blue （MB）. Due to the mixture of adsorption and photodecomposition, the concentration of MB, organic pollution, in water decreased rapidly with TiO2-mounted halloysite powder, which is a faster reaction than that with halloysite-only adsorption. This new use of halloysite is leading to many interesting applications in the decomposition and elimination of various pollutants in air and water.     

“Drastic”法在贵州省主要城市地下水防污性评价中的运用

据贵州省主要城市环境地质调查项目资料,通过对地下水防污性评价单元划分,采用drastic指标法对城市人口密集区地下水防污性进行评价,将贵州省主要城市防污性进行分区划分出防污性好—防污性差五个等级,以利于政府在城市规划建设中对提高城市地下水防污性能采取积极有效的保护措施。
