Hydrolýza bojových látek s využitím biosyntetizovaných zlatých nanočástic

Abstract

The thesis focuses on the biosynthesis of gold nanoparticles using algae Mallomonas kalinae and their use in a decontamination of warfare agents. Theoretical part deals on general characterization of nerve agents, their detection, decontamination and degradation. In the practical part biosynthesized gold nanoparticles were characterized using mostly transmission electron microscopy and X-ray diffraction. Suspension of gold nanoparticles was used as catalyst for hydrolysis of soman (3,3-dimethyl 2-butyl methylphosphonofluoridate) and VX (O-ethyl S-2-(diisopropylamino)ethyl methylphosphonothionate). Reaction of chemical warfare agent VX and soman with gold nanoparticles have been studied using gas chromatography with mass spectroscopy detector and solid-phase microextraction.
