Synthesis and characterization of monoazathiacrown ethers as ionophores for polymeric membrane silver-selective electrodes

Characterization of a Ag+-Selective Electrode Based on Naphthalimide Derivative as Ionophore

“…The favorite donor binding site atom based on the hard-soft acid base (HSAB) concep t is still the primary factor, [1] so the most of the reported heavy metal ionophores for use in ion selective electrodes (ISEs) possess sulfur and/or nitrogen ato ms. [2] Among the heavy metal io ns, Ag + has attracted the interest of researchers, and many compo unds have been used to construct Ag + -ISEs. [2][3][4] Among these compounds, crown ethers show strong ability to form remarkably stable and selective complexes with heavy metal ions and have been found to exhibit interesting host-g uest complexatio n characteristics. [3] Especially, crown ethers containing nitrogen and sulfur donor atoms are of interest as they exhibit high affinities towards Ag + .…”

N-Unsubstituted-1,2,3-triazole-tethered, AIEE type conjugated polymer as a ratiometric fluorescence probe for silver ions

“…By comparing with other traditional Ag + detection methods, such as atomic absorption, plasma emission spectroscopy, anodic stripping voltammetry and potentiometry, etc, [8][9][10] optical probing for Ag + displayed some attractive advantages, such as good selectivity, low detection limit, convenience in sample preparation and relative low-cost of related equipments. [11][12][13] Despite of the available advances Ag + optical probes have been achieved, two main obstacles are still laying before the further application and improvement of these probes.…”

Thiodiethanethiol Modified Silica Coated Magnetic Nanoparticles for Preconcentration and Determination of Ultratrace Amounts of Mercury, Lead, and Cadmium in Environmental and Food Samples

“…Although 2, 2 0 -thiodiethanethiol and its derivatives exhibited excellent selectivity toward Ag þ ions as an ion-selective electrode (J. Zhang et al 2010), according to a literature survey, no preconcentration study has been performed using thiodiethanethiol modified silica coated magnetic nanoparticles for determination of metal ions.…”
