The features of the plasma-erosion method for preparation of Ag nano-dispersed hydrosols resistant to sedimentation and the operation of experimental laboratory equipment for it implementation are described. The results of scanning electron microscopy of nanodispersed plasma-erosive Ag particles and their size distribution are presented. A method and the results of a comparative analysis of the bactericidal effect of aqueous solutions of Ag ions and nanoparticles on Escherichia coli 1257 and their fungicidal effect on Candida albicans and Aspergillus niger F-171 at various concentrations and duration of action of the drugs are presented. Recommendations on the application of the described preparation forms of disinfectants are given.
Key words: plasma-erosion dispersion, Ag nanosize particles, hydrosols, discharge pulses, Escherichia coli, Candida albicans, Aspergillus niger, bactericidal effect, fungicidal effect.
