Abstract
Preparation of a New Sol-Gel Molecularly Imprinted Polymer with Isatin Template for an On-Line SolidPhase Extraction of HMF from Fruit Juice Samples
Highlights
Sample preparation refers to a group of methods in which a sample is prepared for specific chemical analysis or improved the conditions of that analysis [1]
The present paper introduces a new MIS polymer by combining the imprinting technique with a sol-gel process utilizing isatin as a dummy template
The prepared polymer was used as the sorbent of the solid-phase extraction (SPE)-minicolumn in an online-SPE-high-performance liquid chromatographic (HPLC) technique
Summary
Sample preparation refers to a group of methods in which a sample is prepared for specific chemical analysis or improved the conditions of that analysis [1]. In recent past years, using of molecularly imprinted polymers (MIPs) and molecularly imprinted sol-gel materials (MIS) have been significantly extended for the preparation of high-selective sorbents to improve the SPE techniques selectivity. Polymers synthesized by the sol-gel processes are prepared under gentle conditions, possess high chemical and temperature resistance, and are very suitable for online SPE [6].
