Synthesis of Molecularly Imprinted Polymer for Selective Solid-Phase Extraction of Salbutamol from Urine Samples
A highly selective methacrylic based molecularly imprinted polymer (MIP) was synthesized and applied for the separation and the pre-concentration of salbutamol in urine samples. Spectrophotometric determination of salbutamol was achieved using 2,6-dichloroquinone chlorimide as colorimetric reagent. The detection limit of the method was ca. 13 ng mL in urine after pre-concentration of the sample...
متن کاملExtraction of crocin from saffron (Crocus sativus) using molecularly imprinted polymer solid-phase extraction.
A new molecularly imprinted polymer for extraction of crocin from saffron stigmas was prepared using gentiobiose (a glycoside moiety in crocin structure) as a template. Crocin binding to gentiobiose imprinted polymer (Gent-MIP) was studied in comparison with a blank nonimprinted polymer in aqueous media. Affinity of the Gent-MIP for the crocin was more than the nonimprinted polymer at all conce...
متن کاملSynthesis and Evaluation of a Molecularly Imprinted Polymer for Selective Solid-Phase Extraction of Irinotecan from Human Serum Samples
A molecularly imprinted polymer (MIP) was synthesized by non-covalent imprinting polymerization using irinotecan as template. Methacrylic acid and 4-vinylpyridine were selected as functional monomers. An optimized procedure coupled to LC-PDA analysis was developed for the selective solid-phase extraction of irinotecan from various organic media. A specific capacity of 0.65 µmol•g-1 for the MIP ...
متن کاملSynthesize of Ion Imprinted Polymer for Selective Extraction of lead (II) from Environmental Water Samples
A new Pb(II) imprinted mercapto functionalized Montmorillonite was synthesize by an easy one step reaction by combining a surface imprinting technique for selective phase extraction of Pb(II) prior to its determinations by flame atomic absorption spectroscopy. The modified sorbent was characterized by FTIR and studied for preconcentration and determination of Pb(II) in natural water samples. Th...
متن کاملSelective Extraction and Determination of Di(2-ethylhexyl) Phthalate in Aqueous Solution by HPLC Coupled with Molecularly Imprinted Solid-phase Extraction
Surface Molecularly Imprinted Polymer (SMIP) for selective adsorption of di(2-ethylhexyl) phthalate(DEHP) was prepared on the surface of silica gel which was modified by aminopropyltriethoxysilane and acryloyl chloride in a two-step method. The prepared SMIP was used to prepare Molecularly Imprinted Solid-Phase Extraction (MISPE) column for selective extraction of DEHP from aqueous solution...
