Antibacterial and Antifungal Glass with High Biocide Performance: Increased Antimicrobial Efficiency by Acid Activation

Abstract:

Article Preview

A compound contending silver ion specimens presents biocidal properties with effect proportional to ion concentration. An efficient biocidal material can be developed by incorporating silver ions species in glasses by ionic exchange process. The reactive area and material porosity are factors that influence the ion exchange reaction efficiency. Previous studies show that the acid activation of glasses increases the absorption capacity and can also increase the exchange capacity. This paper presents preliminary results on the biocide potencial optimization of the biocide powder glass. This process was performed using hydrochloric acid. Different pH (1.00, 3.00 and 5.00), treatment time (2.0, 4.0 and 6.0 hours) and temperature (30.0, 60.0 and 90.0°C) were used in the samples development. Microbiological analysis of the samples was made by disk diffusion method in the bacteria species Echerichia coli and Staphylococcus aureus. Samples were still submitted to EDS and Atomic Absorption.
