“…It is known that the perchlorate salts have been used to treat patients with hyperactive thyroidglands and to carry out diagnostic tests. 2 Various analytical methods such as volumetric titrations, 3 gravimetry, 4 spectrophotometry, 5 atomic absorption spectrometry 6 and ion chromatography 7 have been used for determination of perchlorate. Most of these methods are susceptible to interference from different cationic or anionic species, are either time-consuming and/or need sophisticated instruments and require the expensive instrumentation and/or extensive sample pretreatment.…”

A highly selective poly(vinyl chloride) (PVC) membrane electrode based on Co(III)-Schiff base [Co(5-NO 2 -Salen)(PBu 3 )]ClO 4 •H 2 O (where 5-NO 2 -SalenH＝bis(5-nitrosalycilaldehyde)ethylenediamine) as a new carrier for construction of perchlorate-selective electrode by incorporating the membrane ingredients on the surface of a graphite electrodes has been reported. The proposed electrode possesses a very wide Nernestian potential linear range to perchlorate from 1.0×10 -6 to 5.0×10 -1 mol•L -1 with a slope of (59.4±0.9) mV per decade of perchlorate concentration with a low detection limit of 5.0×10 -7 mol•L -1 and good perchlorate selectivity over the wide variety of other anions. The developed electrode has an especially fast response (＜5 s) and a wide pH independent range (3.0-12.0) in comparison with recent reported electrodes and can be used for at least 2 months without any considerable divergence in their potential response. This electrode was used for the determination of perchlorate in river water, drinking water, sludgy water and human urine with satisfactory results without complicated and time consuming pretreatment.

“…As is known, few selective methods for determining this anion are found in the literature [8][9][10][11][12][13]. Among these, the majority are potentiometric methods which employ a membrane [8-10] solid contact electrode [11,12] and HPLC methods [13]. Thus, the possibility of using this material to prepare a :membrane specific for this anion appears to be very attractive in as much as the altached pyridinium ion is chemically very stable [4,14].…”

Potentiometric study using chemically modified silica gel with pyridinium as membrane for ClO 4 − ions

et al. 1995

Abstract.A potentiometric sensor for the perchlorate anion was developed by mixing chemically modified silicagel with pyridinium perchlorate, with an epoxy polymer and graphite. The electrode showed Nernstian response between 1.0 x 10 .2 and 1.0 x 10 3 M perchlorate concentrations. The electrode showed high selectivity to this ion at solutions pH between 5.5 and 8.0. The presence of IO2,NO3,Br-,IO2,C1-and SO 2-ions in the solutions, had only small interference in the electrode response in the range mentioned.Key words: modified silica gel, pyridinium ion, perchlorate analysis, perchlorate selective electrode.Silica gels chemically modified with organofunctional groups have been used to adsorb metal ions from solutions [1][2][3][4], in preconcentration and further analysis of metal ions present at trace levels [5] and for the separation and determination of metal ions using high pressure liquid chromatography [6].In a previous study it was shown that pyridinium ions, covalently attached to a silica gel surface, have a high selectivity for the C10 4 ion [7]. As is known, few selective methods for determining this anion are found in the literature [8][9][10][11][12][13]. Among these, the majority are potentiometric methods which employ a membrane [8-10] solid contact electrode [11,12] and HPLC methods [13]. Thus, the possibility of using this material to prepare a :membrane specific for this anion appears to be very attractive in as much as the altached pyridinium ion is chemically very stable [4,14]. The ion selective electrode fi)r the perchlorate ion can be very importani to determine perchlorate present in complexes, explosives and solid propellants.In this work the use of an electrode membrane made with this material is described. Results of a study of the chemical selectivity, stability and the effect of the solution pH on the electrode response are reported.

“…Several different methods comprising volumetric titration [13], gravimetry [14], spectrophotometry [15], atomic absorption spectrometry [16,17], and ion chromatography [10] have been used for the determination of perchlorate ions. However, most of these techniques have various disadvantages such as long analysis time, need for sophisticated devices, laborious pretreatment processes, high-cost measurements and need for experts.…”

A potentiometric perchlorate-selective electrode based on a phenanthroline derivative, neocuproine (2,9-dimethyl-1,10-phenanthroline), was developed. An electroactive substance, a neocuproine complex of Cu 2+ , providing a selective response to perchlorate was formed in situ in the electrode membrane structure during the conditioning process. Membrane optimization studies showed that the most suitable membrane composition was 1.0% (w/w) neocuproine, 69.0% (w/w) o-nitrophenyloctylether (o-NPOE) and 30.0% (w/w) poly(vinyl chloride) (PVC) in terms of potentiometric performance characteristics. For the proposed electrode, the linear range, slope, detection limit, pH working range and response time were determined as 2.5 × 10 -7 -1.0 × 10 -1 M, -53.01 mV/decade, 1.0 × 10 -7 M, 4.0-12.5 and ≈3 s, respectively. The proposed sensor was successfully used in the determination of perchlorate contents of some perchlorate spiked tap, river and dam water samples.
