Abstract

Namen diplomske naloge je bil spremljanje razpada razredčenih vodnih raztopin vodikovega peroksida pri različnih koncentracijah ter preučevanje vpliva citronske in dipikolinske kisline na njihovo stabilnost. Razpad vodikovega peroksida sem spremljala s stresnim testom z zasledovanjem začetne in končne koncentracije raztopin, pred in po segrevanju po 16 urah pri 96 °C, z namenom ugotoviti, katera izmed testiranih kislin bolje stabilizira razredčene vodne raztopine vodikovega peroksida. Takšne raztopine vodikovega peroksida so primerne za splošno dezinfekcijo in uporabo v prehrambni industriji.

Secondary title: Studies on new formulations of dilute hydrogen peroxide solutions
Secondary abstract: The aim of this work was to observe the decomposition of dilute aqueous solutions of hydrogen peroxide at different concentrations and to study the influence of citric and dipicolinic acids on their stability. The decomposition of hydrogen peroxide was monitored by a stress test in which the initial and final concentrations of the solutions were monitored before and after heating to 96°C for 16 hours. The objective was to determine which of the acids tested more strongly stabilized dilute aqueous solutions of hydrogen peroxide. Such hydrogen peroxide solutions are suitable for general disinfection and use in the food industry.
