TITANIUM OXIDE POROUS PARTICLE FOR BLOOD PURIFICATION, BLOOD PURIFICATION MATERIAL, AND MODULE FOR BLOOD PURIFICATION

摘要

PROBLEM TO BE SOLVED: To provide a blood purification material which uses titanium oxide with photocatalyst activity suppressed even under irradiation with visible rays though the titanium oxide has a large number of stable oxygen defects, and is excellent in adsorption and elimination ability of toxic substances contained in blood and the like, while it eliminates useful substances contained in the blood and the like as small as possible, and is reduced in dusting properties, and a module for blood purification using the blood purification material.SOLUTION: The module for blood purification is formed using a titanium oxide porous particle for blood purification comprising the titanium oxide, in which when the titanium oxide porous particle is measured by an electron spin resonance measurement at a temperature of 10 K, a signal at a value of around 1.96 is present, the signal being divided into two signals representing a component g1 parallel to the axis of symmetry and a component g2 vertical to the axis of symmetry, and a signal at a value of from 2.003 to 2.004 is not substantially present.
