Patent Title: Ethylene equol molecular engram solid phase extracting small pole and its its prepn process
Publication date: 2005
Publication number: CN1601272

Abstract: The invention discloses a molecular impriting solid-phase extraction small column capable of high-selectively purifying and enriching diethyl stiboestrol (DES) from sample solution for determining residual amount of artificially-synthetic estrin diethyl stiboestrol (DES) in animal food and its preparation method. Said invention uses diethyl stiboestrol as molecular template to prepare molecular imprinting polymer, it is a cross-linked polymer with fixed hole size and form and definite arranged function group, and has the 'memory' function for steresotructure of diethyl stiboestrol template molecule, so that said material can be fileld into polypropylene small column so as to can obtain the diethyl stiboestrol molecular imprinting solid-phase extraction small column. As compared with general solvent extraction method and C18 solid-phase extraction method said invented imprinting column is more simple, quick and higher in efficiency.
