Lignosulfonate‐stabilized gold nanoparticles (AuNPs‐LS) were synthesized and subsequently used as a complexing agent for mercury ions. The obtained AuNPs‐LS/Hg2+ complex was characterized by means of various physicochemical techniques such as UV‐vis spectroscopy, transmission electron microscopy and cyclic voltammetry. Furthermore, the resulting complex was evaluated as an electrode modifier for the development of amperometric sensors. Upon sufficient negative potential, the bound mercury ions are reduced to form an amalgam with AuNPs‐LS. Thus, the performance of glassy carbon electrode (GCE) modified by AuNPs‐LS/Hg film was investigated as an electrochemical sensor in the determination of Tl+ ions in a 0.05 M EDTA at pH 4.5. The presence of the mercury containing film improves the analyte accumulation due to its ability to form a fused amalgam with thallium. The presented data indicate that the GCE/AuNPs‐LS/Hg modified electrode shows better performance toward Tl+ determination in comparison to bare GCE. The stripping anodic peak current of thallium was linear over its concentration range from 1.7⋅10−7 to 5.0⋅10−6 M. The detection limit (3σ) was estimated to be 1.4⋅10−7 M. The proposed method was successfully applied for the determination of thallium ions in real samples of soil derived from the area of the copper smelter near Głogów (Poland).

Heavy metals ions (HMI), if not properly handled, used and disposed, are a hazard for the ecosystem and pose serious risks for human health. They are counted among the most common environmental pollutants, mainly originating from anthropogenic sources, such as agricultural, industrial and/or domestic effluents, atmospheric emissions, etc. To face this issue, it is necessary not only to determine the origin, distribution and the concentration of HMI but also to rapidly (possibly in real-time) monitor their concentration levels in situ. Therefore, portable, low-cost and high performing analytical tools are urgently needed. Even though in the last decades many analytical tools and methodologies have been designed to this aim, there are still several open challenges. Compared with the traditional analytical techniques, such as atomic absorption/emission spectroscopy, inductively coupled plasma mass spectrometry and/or high-performance liquid chromatography coupled with electrochemical or UV–VIS detectors, bio- and biomimetic electrochemical sensors provide high sensitivity, selectivity and rapid responses within portable and user-friendly devices. In this review, the advances in HMI sensing in the last five years (2016–2020) are addressed. Key examples of bio and biomimetic electrochemical, impedimetric and electrochemiluminescence-based sensors for Hg2+, Cu2+, Pb2+, Cd2+, Cr6+, Zn2+ and Tl+ are described and discussed.

“…A variety of techniques have also been reported in the earlier studies for the detection of thallium ion such as electrochemical or flame atomic emission spectroscopy, electro‐analytical techniques, ETV‐ICP‐MS, FAAS, ICP‐MS, ICP‐AES, GFAAS, neutron activation, and X‐ray fluorescence spectroscopy. But these methods carry a risk of contamination, laborious; require expensive instrumentation, and highly skilled manpower . Hence, development of less expensive, selective, and sensitive technique for the determination of thallium is still enviable.…”

A Thallium Ion Sensor Development Based on the Synthesized (E)‐N′‐(Methoxybenzylidene)‐4‐ Methylbenzenesulfonohydrazide Derivatives: Environmental Sample Analysis

In this research work, three new derivatives of (E)‐Nʹ‐(methoxybenzylidene)‐4‐methylbenzenesulfonohydrazide (MBMBSH) were prepared by means of a condensation technique from the methoxybenzaldehyde and 4‐methyl‐benzenesulphonylhydrazine in good yields, which were crystallized in EtOH and MeOH. MBMBSH ligands were examined through spectroscopic progression (1H‐NMR, 13C‐NMR, FTIR, and UV‐Visible). Structures of the MBMBSH lignads confirmed with a single crystal X‐ray diffraction scheme (SCXRDS). MBMBSH derivatives used for the imminent recognition of heavy metal ion (thallium) based on a reliable current‐voltage (I−V) procedure. Smooth GCE was covered with a light layer of MBMBSH molecules and consequently modified toward a sensitive and selective thallium ion sensor using conducting polymer matrix, Nafion (NF). Analytical parameters such as sensitivity, LOQ, and LOD of GCE/4‐MBMBSH/NF as a sensor were calculated from the calibration plot and found as 622.9 pAμM−1cm−2, 250.0 mM, and 75.0 pM respectively. This prospective sensor (GCE/4‐MBMBSH/NF) applied to the careful determination of thallium ion in spiked environmental samples and found satisfactory result.
