“…[26] Therefore, an accurate and reliable method for the determination of chromium ions is important. The detection of chromium ions in water samples has been performed by a variety of techniques, including electrothermal atomic absorption spectrometry, [27,28] atomic absorption spectrometry, [29] fluorescence spectroscopy, [30][31][32] potentiometric membrane sensing, [33] and electrolysis. [34] Among the many detection methods, colorimetric detection based on gold nanoparticles is particularly attractive for point-of-use applications owing to its low cost, speed, and especially ease of readout (even with the naked eye).…”

The detection of Cr3+ and Cr6+ ions is very important as they are dangerous pollutants and carcinogens. Herein, we describe the preparation of 2,6‐pyridinedicarboxylic acid functionalized gold nanoparticles (PDCA–AuNPs) and their application as colorimetric sensors for the detection of Cr3+ and Cr6+ ions in water samples. The PDCA–AuNPs could be induced to aggregate quickly in the presence of Cr3+ ions, and the aggregation can be observed through the colorimetric response and special localized surface plasmon resonance (LSPR) of the gold nanoparticles. A linear response to the concentration of Cr3+ ions was observed from 10 nM to 1 μM. The detection limit is as low as 2 nM, which is below the maximum recommended contamination level of the World Health Organization for the chromium content (0.962 μM) in drinking water. The highly specific interactions of Cr3+ ions with PDCA–AuNPs provided excellent selectivity towards the detection of Cr3+ ions over other metal ions (Pb2+, Mg2+, Zn2+, Ni2+, Cu2+, Co2+, Ca2+, Mn2+, Fe2+, Cd2+, Ba2+, Cr6+, Ag+, Fe3+, Al3+, and Hg2+). Additionally, Cr6+ ions can be determined through the detection of Cr3+ ions after reduction by ascorbic acid. This method can offer the additional advantage of the efficient detection of Cr3+ and Cr6+ ions over other ions in environmental lake water. Additionally, the PDCA–AuNPs can be used as an efficient catalyst for the reduction of 4‐nitrophenol (4‐NP) and K3[Fe(CN)6].

“…It can be seen in Table 1 that transition and heavy metal ion sensors reported include a PMME (polymeric memberane microelectrodes) for Y 3+ [60], three PMEs [61,63,64] and one CGE [62] for Vanadyl ion, eight PMEs for Cr 3+ [65][66][67][68][69][70][71][72], one of which could also be used in the CGE mode [70], and two Fe 3+ PMEs based on 5,10,15,20-tetrakis(pentafluorophenyl)-21H,23H-porphyrin [73] and 2-[(2-hydroxy-1-propenyl-buta-1,3-dienylimino)-methyl]-4-p-tolylazo-phenol [74].…”

This review presents a general overview about the development of ion-selective electrodes in Iran during the past decade (1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006). All of the reported ion-selective sensors (for cations, anions and organic species) are cited in this review. Sensors for 39 cations, 12 anions, and 23 organic compounds and drugs have been reported in this reivew. Some of the main group cations (e.g. beryllium) as well as most of the lanthanide ion (i.e., presidium, erbium, lutetium, cerium, neodymium, europium, gadolinium, terbium, dysprosium, holmium, ytterbium, and thulium) sensors have been reported for the first time. It is noticable that the best reported sensors for HPO 4 2-, SO 4 2-, Cl -, ClO 4 -, Br -, and I 3 -have been designed and constructed by the Iranian researchers.
