二氧化硅／二氧化钛催化吸附材料的制备及处理含氰废水研究
Preparation of TiO2/SiO2 Composite Catalytic Adsorption Material and Application in Treatment of Cyanide Wastewater
摘要
Abstract
TiO2/SiO2 composite catalytic adsorption material was prepared by three-steps method . Using ethanol as organic solvent ,sodium silicate as silicon resource ,and butyl titanate as a source of titanium ,the final produce was obtained by the sol-gel method ,and aging ,drying and high-temperature roasting .Based on the results of SEM ,thermogravimetric analysis and testing of micromeritics 2020 ASAP ,the material has high specific surface and pore volume .The material is used to treat containing cyanide wastewater ,the results show that the material can adsorb copper cyanide complex ions and photo-catalysis decompose cyanide in wastewater .The rate of adsorption of copper cyanide complex ions is more than 90% ,and the rate of cyanide decomposition is more than 80% .关键词
