“…Due to ISE characteristics, in the last years, their industrial, environmental, agricultural and medical applications are increasing [2,3]. In the last decades, for copper(II) determination, several ion-selective electrodes with solid membrane based on copper sulphide [4,5], tungsten oxide [6], and copper(II) complexes [7 ± 9] and electrodes with liquid membrane [10 ± 12] have been reported.…”

Potentiometric carbon paste electrodes for copper(II) based on dithiosalicylic and thiosalicylic acids are described. The sensor based on dithiosalicylic acid (DTS) exhibits a linear response with a nearly Nernstian slope of 27.7 mV per decade, whereas the electrode based on thiosalicylic acid (TS) shows a super-Nernstian slope. The limits of detection for the DTS sensor and the TS sensor are 10 À 7.9 and 10 À 6.3 M for copper(II) activity, respectively. Selectivity coefficients are tabulated, and the influence of the pH on the response of these ISEs is studied. The DTS electrode is successfully used for potentiometric titration of humic acids with copper in order to get more information about complexing properties of these acids.

“…homogeneous and heterogeneous. The heterogeneous precipitate based ion-exchange membranes have been broadly used as potentiometric sensors [22][23][24][25][26][27][28][29][30][31][32][33]. The wide applicability of ion selective electrodes was due to its good selectivity, low cost, sensitivity and wide range of experimental conditions.…”

Gelatin- Zr (IV) phosphate nanocomposite (GT@ZPNC) and alginate- Zr (IV) phosphate nanocomposite (AG@ZPNC) ion exchangers has been prepared by sol-gel method. The nanocomposites are characterised by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The SEM results of GT@ZPNC and AG@ZPNC confirmed that after the binding of polymer matrix to inorganic part, morphology was completely reformed. TEM results confirmed the synthesised materials were nanocomposite in nature. The GT@ZPNC and AG@ZPNC ion exchangers have been explored to fabricate ion selective electrode for the detection of Cd (II) and Al (III) metal ions. Both ion selective membrane electrodes show wide working concentration and pH range with good response time.

Synthesis, Characterization and Ion Exchange Properties of a New Composite of Inorganic Ion Exchanger: Polyacrylonitrile Cerium(IV) Molybdophosphate

et al. 2012

In this work, the synthesis of the composite of cerium(IV) molybdophosphate (CMP) and polyacrylonitrile (PAN) was reported (CMP-PAN). The material has been characterized by elemental and spectral (FT-IR), X-ray and thermal (TGA) analysis. Also the size analysis of the composite was done by scanning electron microscopy (SEM). Its chemical stability in acidic, basic and saline solutions and radiation stability up to 100 kGy total expose dose were assessed. Whereas the synthesized composite has ion exchange properties, its ion exchange capacity and behavior toward several metal ions were also investigated. Further, the distribution coefficients of the metal ions were calculated. Finally, the ability of the synthesized CMP-PAN composite for the decontamination of low level liquid waste (LLLW) was investigated.
