In this work, three different porogens were used to synthesise PS–MIPs, and the recognition properties and application of the MIPs were evaluated. The results showed that the MIPs that utilised dichloromethane as the porogen exhibited higher binding
capacities than those prepared with n-hexane or n-hexane/dichloromethane
(1:1, v/v). The porogen volume had little to no effect on the adsorption capacities, but it clearly affected the particle size. The biggest particle size of MIP3 (D50 is 5.36 lm) was obtained when 36 mL dichloromethane was used as the porogen.
