Obtaining and characterization of zeolitic materials with antibacterial properties

Abstract

The aim of this work was the preparation, characterization and antibacterial activities testing of copper and silver doped Romanian zeolite. The structural and morphological characterization of copper and silver doped zeolite versus natural zeolite was performed using Laser Induced Breakdown Spectroscopy (LIBS), Scanning Electron Microscopy (SEM) and Infrared Spectroscopy (IR). In addition, natural zeolite doped with copper and silver was electrochemically characterized by using cyclic voltametry (CV) with boron-doped diamond electrode (BDD). The antibacterial activities testing of the two oligoelement doped zeolite was achieved on a real stagnant water sample that belongs to residential area of Timisoara, Romania, studying some microbiological parameters as total coliforms, thermotolerant coliforms (faecal coliforms) and enterococcus (streptococcus faecalis).
