In this study, aniline-formaldehyde polymer was synthesized and then modified with extra aniline as cross-linker in the presence and absence of Ni(II) as the template to produce Ion Imprinted Poly(Aniline-Formaldehyde) (IIPAF) and Non Imprinted Poly(Aniline-Formaldehyde)(NIPAF) The IIPAF was subjected to adsorption, preconcentration and determination of Ni(II) ion in envir...

Fall is burning season in the wheat fields of eastern Washington State. To prepare for planting in 1998, farmers burned about 229,000 acres of wheat stubble, an increase over recent years. Although a tighter state permitting system substantially reduced the acreage burned in 1999, dean air activitists are concerned that the state has not tightened up enough. The fires are used to help control c...

Effect of Chlorpyrifos (Dursban) an organophosphate insecticide on the glycogen, cholesterol, protein, alkaline phosphatase and acid phosphatase in liver in Channa punctatus (Bloch) exhibited notable alterations. Liver being the main site of metabolic activity in body and highly active in both toxifying and detoxifying insecticides, was selected for the study purpose. Chlorpyrifos insecticide c...

A new ruthenium ion imprinted polymer was prepared from the Ru(III) 2-thiobarbituric acid complex (the template), methacrylic acid or acrylamide (the functional monomers), and ethylene glycol dimethacrylate (the cross-linking agent) using 2,2'-azobisisobutyronitrile as the radical initiator. The ion imprinted polymer was characterized and used as a selective sorbent for the solid phase extracti...

In this work a novel ion imprinted polymer (IIP) based on N-(pyridin-2-ylmethyl)ethenamine (V-Pic) was coated on Fe3O4 nano-particles and characterized by thermal gravimetric and differential thermal analysis (TG/DTA), IR spectroscopy, Scanning electron microscopy (SEM) and also elemental analysis. The application of this novel magnetic sorbent was investigated in rapid extraction, preconcentra...

Herein, a novel molecularly imprinted polymer was synthesized on silica nanoparticles via surface imprinting approach for rapid, sensitive and selective detection of atenolol in artificial urine samples. For this purpose, were firstly modified with methacryloxy group initiated polymerization then, carried out the presence 2-hydroxyethyl methacrylate (functional monomer), ethylene glycol dimetha...

A novel Pb(II) ion imprinted polymer coated on magnetic mesoporous silica was synthesised and characterised by scanning electron microscopy (SEM), thermal gravimetric/differential thermal analysis (TG/DTA), elemental analysis (CHN) and low angle X-ray powder diffraction (XRD). The application of this sorbent was investigated in preconcentration and determination of low concentrations of lead io...

a molecular imprinted polymer (mip) was computationally designed and synthesized for the selective extraction of metaproterenol (mtp), from human plasma. in this regards semi empirical mp3 and mechanical quantum (dft) calculations were used to find a suitable functional monomers. on the basis of computational and experimental results, acrylic acid (aa) and dmso:meoh (90:10 %v/v) were found to b...

Silver ion imprinted polymer (IIP) was synthesized in the presence of Ag(I)-N,N’-bis(salicylidene) ethylenediamine (salen) complex using 4-vinylpyridine as the functional monomer, ethylene glycol dimethacrylate (EGDMA) as the crosslinker, and 2,2-azobis(isobutyronitrile) (AIBN) as the initiator. The Ag(I)-imprinted polymer (IIP) particles were characterized by SEM (scanning electron microscope)...
