Ion exchange membrane with antimicrobial effect

Popis výsledku v původním jazyce

The aim of work is to prepare ion exchange membrane with antimicrobial effect used in food industry for filtration of milk. The main problem is to eliminate bacteria from family Enterobacteriaceae such as E. coli or S. aureus from milk which degrade filtration process and lifetime of membrane by congesting and also contamination of milk can rapidly increase which is unacceptable for final consumers. In this study, antimicrobial effect of membrane will be achieved by utilizing silver nanoparticles prepared by various chemical techniques in colloidal state which brings a big advantage of tailoring properties of nanoparticles (size, shape, optical properties) during the preparation process. The second crucial task is to bind nanoparticles onto surface ofpolymeric ion exchange membrane. These bonds should be as strong as possible, thus covalent, to avoid contamination of milk by silver nanoparticles which brings another problem; toxicity of nanoparticles. As the mechanism of antibacterial
