本文对凹凸棒石及Ag/Cu改性凹凸棒石的抗菌性能进行了研究并对其晶体结构、物化性能通过XRD、IR和DSC进行了测试和分析。认为凹凸棒石自身有微弱的抗菌性,经Ag/Cu改性后,其原有晶体结构没有被改变,但抗菌性能得到很大提高,同时铜改性凹凸棒石的耐热性能得到一定提高,并据此分析了经Ag/Cu离子改性的凹凸棒石的抗菌机理。
In this paper, the antibacterial properties of attapulgite and Ag / Cu-modified attapulgite were investigated. The crystal structure and physicochemical properties of the attapulgite were tested and analyzed by XRD, IR and DSC. It is considered that attapulgite itself has a weak antibacterial property, its original crystal structure has not been changed after being modified by Ag / Cu, but its antibacterial property has been greatly improved, and the heat resistance of the copper-modified attapulgite has been improved The antibacterial mechanism of attapulgite modified by Ag / Cu ions was analyzed.
