PURPOSE:To use under severe flow condition an adsorbent increased its mechanical strength by forming the adsorbent by use of columnar calcined hydroxyapatite in which at least one small tubular hole passed through in the perpendicular direction is made. CONSTITUTION:In the hydroxyapatite formed into columnar shape, the small tubular hole passed through in the perpendicular direction is made by physical or chemical method and the hydroxyapatite is calcined at 800-1,500 deg.C, preferably 1,000-1,200 deg.C. The calcined formation is a columnar body of >=100mum column diameter and >=10mum in column height, having the small tubular hole of >=10mum diameter passed through in the perpendicular direction. As the hydroxyapatite particle formed by calcining according to a purpose has strong mechanical strength, the adsorbent is suitable to effectively use under severe flow condition as packing for column chromatography, fixed carrier for microorganism and enzyme.
