Abstract
An indicator and method of use thereof, and indicator system and method of use thereof are provided to determine the degree of an oxidative treatment. An indicator is incorporated into the oxidative treatment. The object and the indicator are subjected to the oxidative treatment. A discoloration of the indicator occurs based on an oxidation of the polymer by a process condition of the oxidative treatment oxidizing the polymer. The discoloration of the indicator is measured against a threshold color value to determine the degree of the oxidative treatment.
Claims28
A method for determining a degree of an oxidative treatment of an object, the method comprising:
- incorporating into the oxidative treatment an indicator, the indicator comprising a polymer;
- subjecting the object and the indicator to the oxidative treatment, a discoloration of the indicator occurring based on an oxidation of the polymer by a process condition of the oxidative treatment oxidizing the polymer;
- and
- measuring the discoloration of the indicator against a threshold color value to determine the degree of the oxidative treatment.
An indicator for determining a degree of an oxidative treatment, the indicator comprising:
- a polymer comprising at least one group selected from an amine, a methylene, and a methine, the group suitable to oxidation responsive to exposure to an oxidative chemical in the oxidative treatment, the oxidation of the group discoloring the indicator.
A system for determining a degree of an oxidative treatment of an object, the system comprising:
- an indicator comprising a polymer suitable to discoloration based on an oxidation of the polymer by a process condition of the oxidative treatment oxidizing the polymer;
- a chamber suitable to receive an object and the indicator, the chamber suitable to subject the object and the indicator to the oxidative treatment including the process condition;
- and
- a color value device suitable to determine the discoloration of the indicator against a threshold color value.
