BASALT TUFA AS A BACTERICIDE FILLER FOR SOME PACKAGING MATERIALS

A dependence of the catalytic and antibacterial activity of some basalt tufa samples on their qualitative and quantitative composition, preliminary thermal and/or chemical treatment conditions were investigated. As seen from the chemical X-ray phase and atom adsorption analyses, the tufa is a highly...

As seen from the chemical X-ray phase and atom adsorption analyses, the tufa is a highly siliceous (Si/Al mass ratio is about 4.7÷5.9) zeolite-like mineral with comparatively high content of iron (68÷74 g/kg), some bioelements (Мg, Ca, К, Na) and microelements (Ti, Mn, Zn, Сu).
