Біоцидна активність осадженого кремнезему з поверхневими сполуками Ag, Cu та Zn
Анотація
Модифікуванням поверхні високодисперсного кремнезему аміно-комплексами срібла, міді та цинку з водного розчину з наступною термообробкою, синтезовано кремнеземні нанокомпозити, що містять поверхневі сполуки срібла, міді та цинку. Концентрація срібла в зразках становила 1–2 %, а міді та цинку – 1–5 %. Біоцидну активність одержаних композитів вивчали по відношенню до 18 різних штамів мікроміцетів, фітопатогенних бактерій і водоростей. Встановлено, що найбільша ефективність спостерігається в зразках кремнезему, модифікованого сріблом/міддю, а також сріблом/цинком.
