CuO/凹凸棒石黏土复合材料的制备及其吸附、抑菌性能研究

Synthesis of CuO/attapulgite composite material and their adsorption and antibacterial properties

以凹凸棒石粘土为载体,采用共混水热法制备了纳米氧化铜/凹凸棒石黏土复合材料前驱体,450℃煅烧后得到凹凸棒石黏土负载的多孔氧化铜复合材料,考察了其吸附、抑菌性能。结果表明,复合材料中CuO的质量分数为50%时,亚甲基蓝色度的去除率达80%以上,对金黄色葡萄球菌和大肠杆菌的增长具有良好的抑制作用。

Attapulgite was used as the matrix of CuO to synthesize a novel kind of composite （CuO/ATP） by depositing CuO on the surface of ATP via hydrothermal reaction method, after 450℃ calcined attapulg- ite load porous copper oxide composite, the adsorption and properties of bacteriostaic were investigated. The resuks indicated that CuO/ATP composite lead an improvement to the antibacterial action of Staphy- lococcus aureus and Escherichia coli. When the CuO quality score for 50% in composite material, the effects of CuO/ATP composite has remarkably enhanced degradation rate of the methylene blue which de- grees above the removal rate of up to 80%.
