Ni(II) ion-imprinted solid-phase extraction and preconcentration in aqueous solutions by packed-bed columns
(Elsevier Science BV, 2004)
Solid-phase extraction (SPE) columns packed with materials based on molecularly imprinted polymers (MIPs) were used to develop selective separation and preconcentration for Ni(II) ion from aqueous solutions. SPE is more ...
Biosorption of cadmium, lead, mercury, and arsenic ions by the fungus Penicillium purpurogenum
(Marcel Dekker Inc, 2003)
The potential use of the fungus Penicillium purpurogenum to remove cadmium, lead, mercury, and arsenic ions from aqueous solutions was evaluated. Biosorption of heavy metal ions reached equilibrium in 4 h. Heavy metal ions ...
Mimicking receptor for methylmercury preconcentration based on ion-imprinting
(Elsevier Science BV, 2007)
Solid-phase extraction (SPE) based on molecularly imprinted polymers (MIPs) were used to develop selective separation and preconcentration for methylmercury ion from complex matrixes. In this study, an ion-imprinting polymer ...
Preconcentration of copper on ion-selective imprinted polymer microbeads
(Elsevier Science BV, 2003)
Molecular recognition-based separation techniques have received much attention in various fields because of their high selectivity for target molecules. Molecular imprinting has been recognized as a promising technique for ...
A new metal chelate affinity adsorbent for Cytochrome c
(Wiley, 2004)
We have prepared a novel metal-chelate adsorbent utilizing N-methaeryloyl-L-histidine methyl ester (MAH) as a metal-chelating ligand. MAH was synthesized by using methacryloyl chloride and L-histidine methyl ester ...
Molecularly imprinted ligand-exchange recognition assay of glucose by quartz crystal microbalance
(Elsevier Advanced Technology, 2005)
Molecular imprinted polymers (MIP) as a recognition element for sensors are increasingly of interest and MIP-quartz crystal microbalance (QCM) have started to appear in the literature. In this study, we have combined quartz ...
L-histidine imprinted synthetic receptor for biochromatography applications
(American Chemical Society, 2006)
We have proposed novel surface-imprinted beads for selective separation of cytochrome c (cyt c) by N-methacryloyl(L)-histidine-copper(II) [MAH-Cu(II)] as a new metal-chelating monomer via metal coordination interactions ...
Removal of phenolic compounds with nitrophenol-imprinted polymer based on pi-pi and hydrogen-bonding interactions
(Elsevier Science BV, 2004)
This work describes a method for the removal of phenolic compounds with a nitrophenol-imprinted polymer from aqueous solution by newly functional monomer, methacrylamidoantipyrine (MAAP), which has pi-pi, and hydrogen-bonding ...
Biomimetic catalysis of an organophosphate by molecularly surface imprinted polymers
(Elsevier Science BV, 2005)
A synthetic polymer selective for paraoxon was prepared by a molecular surface imprinting technique. We have combined molecular imprinting with the ability of histidine to chelate metal ions to create active centrum of ...
Preconcentration of copper using double-imprinted polymer via solid phase extraction
(Elsevier Science BV, 2006)
The aim of this study is to prepare double-imprinted polymers which can be used for the selective removal of Cu(II) ions from synthetic waters. Chitosan-succinate (CS) was choosen as the metal complexing polymer. In the ...
