Vpliv različnih stabilizatorjev na stabilnost vodikovega peroksida

Šadl, Nastja (author), Cerkovnik, Janez (mentor)

V diplomski nalogi sem spremljala vpliv različnih organskih kislin na stabilnost vodne raztopine vodikovega peroksida v daljšem časovnem obdobju. Spreminjanje koncentracije raztopine vodikovega peroksida sem spremljala s pomočjo jodometrične titracije. Cilj naloge je bil ugotoviti, katere od izbranih organskih kislin najbolje stabilizirajo raztopino vodikovega peroksida. Svoje ugotovitve sem zbrala v tabelah in prikazala grafično. Eksperimentalni del je zajemal tudi pripravo in standardizacijo uporabljenih kemikalij.

• Title: The influence of different stabilizers on the stability of hydrogen peroxide

Abstract

In this work the influence of different organic acids on the stability of hydrogen peroxide solution was studied. The changes in the concentration of the hydrogen peroxide solution were followed with iodometric titration. The aim of the work was to determine which of the selected organic acids posses the best stabilizing influence on the hydrogen peroxide solution. The results of the study are presented in tables and graphically. The experimental part also includes the preparation and standardization of the applied chemicals.
