摘要: A new concept for the preparation of selective sorbents with high flow path properties is presented by embedding molecularly imprinted polymers (MIPs) into various macroporous gels (MGs). MIP was first synthetized 17β-estradiol (E2) as template adsorption this endocrine disrupter. The composite gel/MIP (MG/MIP) monoliths were then prepared at subzero temperatures. Complete recovery E2 from a 2 μg/L aqueous solution achieved using polyvinyl alcohol (PVA) MG/MIP whereas only 49-74% removed non-imprinted (when no used). PVA monolith columns operated almost 10 times higher rate (50 mL/min) compared to operation 1-5 mL/min. possibility processing particulate containing wastewater effluents rates selectivity on removal, well easy monoliths, make systems attractive and robust clean up water disrupting trace contaminants.
