“…[36][37][38][39][40]26,41,42 Although, many rhodamine based sensors for Fe 3+ have been reported, 43,44 only few of them have been applied in biological systems for the detection of Fe 3+ . 45,46 Due to the paramagnetic nature of Fe 3+ ions, the majority of fluorescent chemosensors for Fe 3+ are fluorescence quenchers, [47][48][49] which certainly hinder fluorescence imaging in vivo and in situ monitoring. Moreover, the reversibility of fluorescence chemosensors is also an important aspect for practical http applications.…”

“…Because the concentration of iron in coastal water is relatively lower, the accurate determination of iron concentrations in coastal water is one of the challeng-ing problems in environmental analysis. Many techniques have been developed to determine iron such as spectrophotometry [6,7], atomic absorption spectrometry (AAS) [8,9], inductively coupled plasma-mass spectrometry (ICP-MS) [10] and fluorescence [11], etc. However, most of the methods need for expensive and bulky devices which restrict their use for in situ determination.…”

a b s t r a c tAn electrochemical sensor based on reduced graphene oxide (rGO) and gold nanoparticles (AuNPs) modified electrode was utilized for determination of trace iron in coastal waters with the aid of the iron complexing ligand 2-(5-bromo-2-pyridylazo)-5-diethylaminophenol (5-Br-PADAP). 5-Br-PADAP reacted with iron in short chelating reaction time (<3 min). rGO as a support provided large specific surface area for AuNPs, which would facilitate the electrochemical reduction of Fe(III)-5-Br-PADAP. Under the optimized conditions, the response of Fe(III) at this resulting sensor was linear in the range of 30 nM to 3 M with a detection limit of 3.5 nM. This sensor also had excellent reproducibility and repeatability. Additionally, the modified electrode had been successfully applied to the determination of Fe(III) in real coastal waters.

A new approach was developed for sensitive determination of Fe(III) and Cu(II) ions using SnO 2 nanopowder in the micellar medium on the contrary conventional cloud point extraction studies. The presented method contains a combination of solid-phase extraction and cloud point extraction. According to this procedure, the metal ions were firstly retained on modified SnO 2 nanopowder and then passed to the surfactant-rich phase. The effect of experimental variables including pH, concentration of reagents, eluting solution, incubation time, equilibration temperature, sample volume, and effects of interfering ions have been investigated and optimized systematically. The calibration graphs were linear in the range of 0.23-100.00 μg L −1 and 0.30-110.00 μg L −1 for Fe(III) and Cu(II), respectively. Under optimized conditions, the limits of detections were 0.07 and 0.09 μg L −1 for Fe(III) and 0.09 μg L −1 for Cu(II). The proposed method offers satisfactory analytical features by means of combining two different and efficient preconcentration techniques. In addition, the method can be evaluated as an alternative and fast method according to only-surfactant-mediated extractions. The validation of method was carried out by recovery tests and certified reference material (CRM) analysis. The acceptable and compatible results were obtained in the analysis of CRM and real samples.
