Abstract
Agents containing polyaniline of one or more specified kinds shown by Formulas (1)-(4) given below can generate active oxygen efficiently and economically when contacted with a liquid having oxygen dissolved therein: ##STR1## where A is a negative ion, n is an integer between 2 and 5000, x and y are numbers such that x+y=1 and 0.ltoreq.y.ltoreq.0.5.
Claims12
A method of generating active oxygen, said method comprising the step of causing a liquid having oxygen dissolved therein to contact an agent comprising polyaniline which is one or more selected from the group consisting of compounds shown by Formulas (1)-(4) given below:
- ##STR3## where A is a negative ion, n is an integer between 2 and 5000, and x and y are numbers such that x+y=1 and 0.ltoreq.y.ltoreq.0.5.
A method of generating active oxygen, said method comprising the steps of causing a liquid having oxygen dissolved therein to contact an agent comprising polyaniline and carrying out electrolysis in said liquid with a cathode having a surface covered with a membrane comprising said agent, thereby causing oxygen in said liquid to receive an electron from the polyaniline in said agent to become superoxide.
A method of generating active oxygen, said method comprising the steps of causing a liquid having oxygen dissolved therein to contact an agent comprising polyaniline and filtering, drying and reusing said agent.
