Abstract
A hazardous substance treatment agent has a retainer and a transition metal oxide. The retainer has the specificity of retaining only a specific hazardous substance, such as a virus, a bacterium or a toxin, that has become mixed in or has the possibility of becoming mixed in a treatment subject, such as blood, that is in at least either a liquid or gaseous phase. By a photocatalytic action, the transition metal oxide inactivates said hazardous substance retained by the retainer.
Claims22
A hazardous substance treatment agent including:
- a retainer having the specificity of retaining only a specific hazardous substance that has become mixed in or has the possibility of becoming mixed in a treatment subject that is in at least either a liquid or gaseous phase, wherein said retainer has amino groups or is a protein, and
- a transition metal oxide for inactivating by a photocatalytic action the hazardous substance retained by said retainer.
A hazardous substance treatment agent having:
- a selective retaining function based on amino groups or protein to retain only a specific hazardous substance that has become mixed in or has the possibility of becoming mixed in a treatment subject that is in at least either a liquid or gaseous phase, and
- a photocatalytic function that inactivates the hazardous substance retained by said selective retaining function.
A hazardous substance treatment method which calls for:
- a hazardous substance treatment agent that has:
- a retainer having the specificity of retaining only a specific hazardous substance and
- a transition metal oxide having the photocatalytic ability to inactivate a hazardous substance retained by said retainer, wherein said retainer has amino groups or is a protein, wherein said method comprises:
- bringing a treatment subject, which is in at least either a liquid or gaseous phase and in which said hazardous substance is either contained or presents the possibility of becoming mixed, into contact with said treatment agent, and
- irradiating said transition metal oxide with light.
