Cadmium (II) imprinted 3-mercaptopropyltrimethoxysilane coated stir bar for selective extraction of trace cadmium from environmental water samples followed by inductively coupled plasma mass spectrometry detection

Hg2+ion-imprinted polymers sorbents based on dithizone–Hg2+chelation for mercury speciation analysis in environmental and biological samples

“…4,[20][21][22][23][24] In contrast to MIPs, IIPs recognize inorganic ions aer imprinting, especially metal ions. 20,21,[24][25][26][27] This recognition ability can be explained by the memory effects of polymers toward metal ion interaction with a specic ligand, coordination geometry, metal ion coordination number, charge and size. 28 Metal IIPs have attracted increasing attention due to their unique features: rst, the coordination reaction is stronger than the hydrogen bond strength, especially in aqueous solution; second, it is quick to achieve the balance of the thermodynamics and kinetics.…”

Solid Phase Extraction to On-Line Preconcentrate Trace Cadmium Using Chemically Modified Nano-Carbon Black with 3-Mercaptopropyltrimethoxysilane

“…6 The determination of cadmium ions has been usually carried out through spectroanalytical techniques such as flame atomic absorption spectrometry (FAAS), 1,7 graphite furnace atomic absorption spectrometry (GF AAS) 8,9 and inductively coupled plasma optical emission spectrometry (ICP OES). [10][11][12] The interest in FAAS comes from their high selectivity and low cost. However, due to the high limit of detection (LOD) of this technique, conventional separation enrichment procedures, mainly the solid phase extraction (SPE) ones, have been frequently used to overcome interferences from matrix elements and to improve the limits of detection.…”

Grafting 3-mercaptopropyl trimethoxysilane on multi-walled carbon nanotubes surface for improving on-line cadmium(II) preconcentration from water samples

“…It is very well known that cadmium is extremely toxic even at low concentrations; it occurs in almost all soils, surface waters and plants, and since it is a cumulative element, it is readily mobilized by human activities [2,3].…”
