Abstract
An adsorbent, which can be produced by a method in which a particle size, a pore size, a specific surface area or the like can be easily controlled, and is suitable for isolation of biomolecules. The adsorbent contains aggregates of calcium phosphate-based particles, and has an average pore size of 15 to 36 nanometers and a specific surface area of 40 to 90 m2/mL when measurement is carried out by mercury porosimetry.
Claims16
An adsorbent, comprising aggregates of calcium phosphate-based particles and having an average pore size of 15 to 24 nanometers and a specific surface area of 50 to 90 m2/mL when measurement is carried out by mercury porosimetry.
A method for producing an adsorbent, comprising:
- (a) spray-drying slurry containing calcium phosphate-based particles having an average major-axis size of 20 to 50 nanometers to obtain aggregates of calcium phosphate-based particles, and
- (b) calcining the aggregates of calcium phosphate-based particles at a temperature of 100 to 600° C.,
- wherein the produced adsorbent comprises aggregates of calcium phosphate-based particles and has an average pore size of 15 to 24 nanometers and a specific surface area of 50 to 90 m2/mL when measurement is carried out by mercury porosimetry.
