Synthesis of a Molecularly Imprinted Polymer for Dioxin

A molecularly imprinted polymer for recognising selectively 2,3,7,8- tetrachlorodibenzodioxin (TCDD) was made by a new non-covalent method employing a “dummy” template. The proposed way represents a simplification of a synthetic scheme proposed by Lübke et al. for covalent imprinting. Comparison of extraction yields of the novel polymer, a non imprinted polymer and an imprinting polymer, prepared by the original procedure demonstrates the binding capacity of the proposed polymer, which is in principle applicable to solid phase extraction (SPE) of dioxin.
