Multi-functional porous organic polymers for highly-efficient solid-phase extraction of β-agonists and β-blockers in milk.

ABSTRACT: A simple, accurate, and highly sensitive analytical method was developed in this study for the determination of ten β-agonists and five β-blockers in milk. In this method, new adsorbent phosphonic acid-functionalized porous organic polymers were synthesized through a direct knitting method. The synthesis procedure of the materials and the extraction conditions (such as the composition of loading buffer and eluent) were optimized. Benefitting from the high surface area (545-804 m² g^-1), multiple functional framework and good porosity, the phosphonic acid-functionalized porous organic polymers showed a high adsorption rate and high adsorption capacity for β-agonists (224 mg g^-1 and 171 mg g^-1 for clenbuterol and ractopamine, respectively).
