Synthesis by precipitation polymerization of molecularly imprinted polymer for the selective extraction of diclofenac from water samples

►A MIP was synthesized by precipitation polymerization using DFC as template.► The MIP had better selectivity and higher adsorption efficiency for DFC. ►The MIP is an effective method for selective extraction of DFC from complex water. ►MISPE is a potentially competitive technique with traditional SPE for its selectivity.
