Synthesis and Characterization of Nanopore Mo^VI-Imprinted Polymer and Its Application as Solid Phase for Extraction, Separation and Preconcentration of Molybdenum Ions from Water Samples

Abstract

The purpose of this study is to prepare a new ion imprinted polymer for Mo VI with high selectivity. Ion-imprinted polymer (IIP) particles were synthesized by thermally copolymerization. For the synthesis of the ion imprinted polymer, the ion pair of (Mo VI -thiocyanate) and NR 4 + was used. The ion pair was precipitated in an aqueous phase and then dissolved in acetonitrile as a porogen. The imprinted ion was removed using 10% (v/v)

Mean drop behavior in the standard liquid–liquid extraction systems on an L-shaped pulsed sieve-plate column: experiment and modeling

“…This methodology includes mathematical and statistical methods derived from the empirical models obtained by relating experimental data to setup and using a second-order polynomial model equation. 62 One of the aims of RSM is optimization throught (1) diagnosis and expression of the problem, (2) selection of response variable, (3) selection of effective parameters and their ranges, (4) selection of an experiment design including the number of experiments, repetitions, blocks, and the order of the experiments, (5) performance of experiments, (6) data analysis to provide an empirical relationship by a convenient polynomial model, (7) the model's fitness evaluation to experimental data, and (8) optimization of the studied variables: 63 where, Y is the predicted response (SMD or d 32 ) reported in Table 6 for the vertical and horizontal sections. The independent factors are X i and X j are and β 0 is a constant corresponding to the central point of experimental variables.…”

Photopolymerization and Photostructuring of Molecularly Imprinted Polymers

“…MIPs are synthetic polymers displaying high affinity and selectivity for analytes ranging from ions − to small organic molecules, − peptides, − biomacromolecules like proteins, − viruses, − and whole cells. , In the majority of the reports, a template polymerization approach is used; that is, a polymer is synthesized in the presence of a molecular template, which results in the generation of specific “cavities”. There are a few examples, though, where MIPs have been obtained from preformed polymers which are molded around the template. , In the template polymerization approach, the crucial step in the preparation of a MIP involves the formation of a prepolymerization complex based on noncovalent interactions , (or in some cases, reversible covalent bonds) between functional monomers and a target molecule, or a derivative thereof, which serves as the template (Figure ).…”

In vitro speciation of molybdenum in human biological samples based on thiol functionalized mesoporous silica nanoparticles and hexyl-methylimidazolium tris-pentafluoroethyl-trifluorophosphate

“…The ILs as a green solvent were used for extraction or separation ions from liquid phases. Recently, the sample preparation such as liquid-liquid microextraction (LLME) [15,17], flow injection chemiluminescence method combined with controlled potential electrolysis technique [18] and solid phase extraction based on inductively coupled plasma-optical emission spectrometry (ICP-OES (SPE) [19][20][21]…”
