Preparation of antibacterial zeolite of different silver-zinc adding sequence and study of antibacterial properties

According to the problem of higher water bacteria content in the municipal sewage treatment plant,to reduce bacteria content of water,combined with domestic and international relevant research,put inorganic cation into the natural zeolite to remove escherichia coli,loading in natural zeolite to adjust and control zeolite particle surface and pore size,to improve antibacterial properties.This experiment mainly test the loading efficiency and bactericidal rate of composite zeolite of different silver-zinc ion adding order,we get the result that the best ion loading efficiency was which adding zinc nitrate after silver nitrate,it increases 3.2% and the highest antibacterial rate can reach 96.36%.The results of SEM-EDS analysis show that the surface of antibacterial zeolite was obviously changed.Specific surface area and pore size both reduced through the related examination.
