Summary
Molecularly imprinted polymers for 1-methyl-2-piperidinoethylester of 2-methoxyphenylcarbamic acid (template) have been synthesised. Acrylamide and methacrylic acids, respectively, were used as the functional monomers. Imprinted polymers were used as the sorbents for solid-phase extraction (MISPE). The capacity and selectivity of prepared imprinted polymers were investigated with the use of some derivatives of 1-methyl-2-piperidinethylesters of alkoxyphenylcarbamic acids. The non-imprinted (blank) polymers were prepared by the same way without a template to study the non-specific interactions. The molecularly imprinted polymer prepared from methacrylic acid was used to preconcentrate 1-methyl-2-piperidinoethylester of 2-methoxyphenylcarbamic acid and its analogues from spiked human plasma (1 μg in 1 ml of plasma).
Key words:
esters of alkoxyphenylcarbamic acids – HPLC – imprinted polymers – solid phase extraction
