Selective removal of 17 beta-estradiol at trace concentration using a molecularly imprinted polymer
(2007) In Water Research 41(12). p.2825-2831- Abstract
- A molecularly imprinted polymer (MIP) was synthesized with 17 beta-estradiol (E2) as template. It was then capable to recover this compound by 100 +/- 0.6% from a 2 mu g/L aqueous solution. By comparison, E2 recoveries of 77 +/- 5.2%, 87.1 +/- 2.3% and 19.1 +/- 7.8%, were achieved using a non-imprinted polymer (NIP) synthesized under the same conditions (but without template), a commercial C18 extraction phase and granular-activated carbon (GAC), respectively When fluoxetine hydrochloride and acenaphthene were added as interferences to the aqueous solution at 2 mu g/L each, E2 was recovered by 95.5 +/- 4.0% from the MIP, compared to 54.5 +/- 9.4%, 76.0 +/- 2% and 14.3 +/- 0.1% from the NIP, C18 and GAC phases, respectively Estrogenic...

This suggested the imprinted polymers removed estrogenic compounds. This study therefore demonstrates the potential of MIPs for the selective removal of endocrine-disrupting compounds. By using a synthetic analogue to natural hormone receptors, adsorption is based on the same property that makes the contaminants harmful. Biological treatment of enriched E2 was also demonstrated.
