Automated system for spectrophotometric detection of liquid phase hydrogen peroxide for concentrations up to 5% w/w.
An automated flow injection analysis system for H(2)O(2) detection in the liquid phase, based on the photometric determination of the complex between hydrogen peroxide and a titanium (IV) reagent is presented. The system was tested for monitoring the H(2)O(2) concentration in a lab-scale experimental setup for H(2)O(2) direct synthesis. In its final configuration, the developed system allows a reliable and reproducible determination of H(2)O(2) for a broad concentration interval between 1.02x10(-3) mol l(-1) and 1.16 mol l(-1).
