eng	Covalent molecularly imprinted polymers for selective adsorption of 1-naphthaleneacetic acid	Molecularly imprinted polymers (MIPs) are specific sorption material capable of either specifically removing interfering substances from the sample for further analysis or to capture the desired analyte from the solution, desorb it and analyse it. In this work we use covalent method for preparing of MIPs, which is however less common like non-covalent method1. MIPs prepared in this work, were designed for the adsorption of 1-naphthaleneacetic acid (NAA) and molecular imprinting was performed by using 2 different NAA derivatives, differing in the length of the hydrolysable linker between template and polymerizable group, in order to reach custom-made cavity providing higher selectivity. Used hydrolysable linkers were ester and N-methylhydroxamate functionality, when both provided high effectivity, but practical nuances between these 2 MIPs were also discovered. A lot of SPE parameters were optimized, provided novel sorption material for quantitative (>98 %) adsorption/desorption of 1-naphtaleneacetic acid, which can be used at least 10 times without lost of activity. Activity, capacity, reusability and selectivity of MIPs were also confirmed in continuous flow system.	Molecularly imprinted polymers (MIPs); 1-naphthaleneacetic acid; selective adsorption
