ABSTRACT:
The sensor electrode has a sensing surface intended to contact a liquid medium for continuous measuring, in combination with a counter electrode and a reference electrode, of the hydrogen peroxide concentration over a concentration range from 0.005 mole/liter to 3 mole/liter, said sensor consisting of a carbon electrode having an open circuit potential between -65 and -85 mV, said open circuit potential being measured with respect to a Ag/AgCl/saturated Cl.sup.- reference electrode in an alkaline solution having a pH between 10.5 and 14, said solution containing hydrogen peroxide at a concentration of more than 0.5 mole/liter.
