<p>Disclosed are: an adsorbent which enables highly efficient and excellently selective solid phase extraction of a solute with a wide range of chromatography polarity, including high-polarity solute molecules, while suppressing adsorption of impurities; and a solid phase extraction method. Specifically disclosed is a heterocyclic ring-containing copolymer adsorbent which is characterized by being composed of a copolymer that is formed from a multifunctional heterocyclic ring-containing monomer, which has a heterocyclic ring that contains at least two heteroatoms in the ring structure, and a monomer that is copolymerizable with the multifunctional heterocyclic ring-containing monomer. The heterocyclic ring-containing copolymer adsorbent is also characterized in that the main chain structure of the adsorbent is configured of the multifunctional heterocyclic ring. Also specifically disclosed is a solid phase extraction method which comprises a step wherein a solution, which contains low-polarity solute molecules, medium-polarity solute molecules or high-polarity solute molecules as a solute, is brought into contact with the heterocyclic ring-containing copolymer adsorbent so that one or more kinds of solutes are selectively adsorbed and held by the adsorbent.</p> |
