Abstract: Various independent studies have recently demonstrated the potential of Molecular Imprinted Polymer (MIPs) as selective adsorbents for the highly efficient removal of EDCs at trace concentration. Current water purification techniques are often inefficient at trace concentration because substances interfering in the removal process are present at higher concentration. Instead, molecular imprinting is based on the same mechanism that makes EDCs so harmful: their capacity to bind to natural receptors, which also makes it possible to remove unknown compounds with endocrine disrupting activity. Molecular recognition is the basis for natural molecules (proteins) to specifically bind to certain substances at extremely low concentrations. In comparison to classical adsorbents, the efficiency of imprinted polymers can be maintained in the presence of interfering matter, and regeneration can be easily achieved by solvent extraction under mild conditions. MIPs are also more stable than bioadsorbents (antibodies, receptor proteins) and can be reused in many cycles. They can finally be synthesized in a vast variety of shape and size. Further research is needed to improve the group selectivity of imprinted materials
