An automated system for the measurement of hydrogen peroxide in industrial applications. [PDF]
J Automat Chem, 1998 An automated sensor system for the continuous and in‐line measurement of hydrogen peroxide in industrial applications is described. The hydrogen peroxide concentration can be measured over the entire pH range, over a wide concentration range of hydrogen peroxide (10-3 70 g/l), from 0 to 70°C, and with high precision and accuracy (errors less than 1% ).
