ABSTRACT:
The present invention provides removing agents comprising a solid substance with a weakly acidic or weakly alkaline surface. Since the removing agents can be used for treating body fluid of a patient by, for example, extra-corporeal circulation system thereby effectively removing human immunodeficiency virus and/or its related compounds contained in the body fluid, it is expected that the life of the patient could be prolonged. The significance of the present invention therefore is great.
