Abstract
The present invention relates to a cellulosic particle body comprising interconnected cellulosic small particles with small interparticle spaces and to a method of producing said cellulosic particle body which comprises dispersing cellulosic small particles in an alkaline medium and contacting the resulting suspension with a coagulating solution. In this specification, the above technology will be referred to as the first invention.
Claims9
An adsorbent for purification of a body fluid which comprises a perfusion type carrier having flow-through pores and sub-pores and, as immobilized thereon, a substance having an affinity for a target substance in the body fluid, and which has a mean particle diameter of not less than 200×10−6 m and produces a perfusion effect when a housing packed with it is irrigated at a liner velocity of not less than 3×10−4 m/s.
