ABSTRACT 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 1.02×10-3 mol   l -1 and 1.16 mol   l -1 .
