Abstract
An optical fiber sensor has been fabricated for detection of 5 M–0.1mM concentrations of hydrogen peroxide with a linear response. The
deposition method used is electrostatic self-assembly (ESA) of polymer cationic and anionic layers. Prussian Blue (PB) has been included
in the polycation layers. The optical fiber sensor is included in a reflection setup, where the measuring technique is based ...

An optical fiber sensor has been fabricated for detection of 5 M–0.1mM concentrations of hydrogen peroxide with a linear response. The
deposition method used is electrostatic self-assembly (ESA) of polymer cationic and anionic layers. Prussian Blue (PB) has been included
in the polycation layers. The optical fiber sensor is included in a reflection setup, where the measuring technique is based on the slope of
the optical reflected power change caused by oxidation of Prussian White (PW) to Prussian Blue. The sensor recovers after immersion in a
reductive agent and is immune against a variety of components. Measurement of hydrogen peroxide has been proved successfully in a wide
range pHs between 3 and 9. Some techniques have been applied in order to avoid the lost of indicator. [--]
