Synthesis and characterization of Hg(II)-ion-imprinted polymer: Kinetic and isotherm studies

Synthesis of an imprinted polymer for the determination of methylmercury in marine products

“…Most of these polymers were synthesized using Hg(II) as template and complexing ligands to produce selective binding sites. The ligands usually contained a sulfur donating atom such as methacryloyl-(L)-cysteine (MAC) [1], aminothiol monomers [2,3], 1-(2-thiazolylazo)-2-naphthol [4],4-(2-thiazolyazo) resorcinol (TAR) [5] and diphenylthiocarbazone [6,7]. Compounds containing amino groups were also used for developing imprinted polymers for Hg(II) removal from aqueous solutions or preconcentration: 3-isocyanatopropyltriethoxysilane (IPTS) [8] bearing thymine (T) bases, diazoaminobenzene-vinylpyridine copolymers [9], tetrakis(3-hydroxyphenyl)porphyrin [10] or a polyaminated chitosan derivative [11].…”

Application of an Hg2+ selective imprinted polymer as a new modifying agent for the preparation of a novel highly selective and sensitive electrochemical sensor for the determination of ultratrace mercury ions

“…Copolymerization of the methacrylic acid as the monomer, and trimethylolpropane trimethacrylate as the cross-linking agent, in the presence of Hg(II)-1-(2-thiazolylazo)-2-naphtholcomplex is another method reported by Dakova et al [55]. Recently, Singh and Mishra [54] have described a new formulation for Hg(II)-ion-imprinted polymer (IIP) by the formation of a binary complex of mercury with 4-(2-thiazolylazo) resorcinol and its thermal copolymerization with methacrylic acid (monomer) and ethylene glycol dimethadrylate (crosslinker), and in cyclohexanol as a porogen.…”

“…This technology can also be used for the preparation of polymers containing inorganic cation selective sites as the so-called ion imprinted polymers (IIP) [49][50][51][52]. Different kinds of imprinted polymers have so far been reported for the recognition of mercury ions [53][54][55][56].…”

Selective solid-phase extraction using molecularly imprinted polymer as a sorbent for the analysis of fenarimol in food samples

“…The kinetics of MIP adsorption had been studied by the Lagergren pseudo-first-order and pseudo-second-order (Du et al, 2013;Singh & Mishra, 2010). 20 mg of MIP was mixed with 2 mL fenarimol standard solution at selective concentrations of 6 lg mL À1 , 12 lg mL À1 , and 24 lg mL À1 .…”

“…The adsorption capability for MIP and NIP was determined by the following procedure (Du et al, 2013;Singh & Mishra, 2010). 20 mg of MIP or NIP was mixed with 2 mL fenarimol standard solution at selective concentration ranging from 1 to 24 lg mL À1 .…”
