Development of new fluorescent probes for mercury ion analysis in environmental or living organism is undergoing quick growth due to its detrimental toxicity to environmental safety, ecological security, and human being. However, in most cases, the industrial waste water is acidic whereas it remains a great challenge to real-time monitor mercury ion directly at low pH using small molecule fluorescence probe. In this study, we have successfully designed and synthesized the Naph (1, 8-Naphthalimide derivative) -based small molecule probe termed as Naph-NSS capable of monitoring mercury ion in a broad range at low pH (from 2.0 to 7.0). The solid spectral studies demonstrated the high sensitivity and selectivity of the probe towards mercury ion among various species. After binding with Hg, the fluorescence of Naph-NSS greatly enhanced, and the mechanism of which was investigated by DFT studies. The probe was able to be loaded on paper strip for instant and fast detection of mercury ions. In addition, the probe is also suitable for detection of mercury ion in environmental samples, living cells and in vivo.

Mercury(II) ions (Hg) are one of the most common and highly toxic heavy metal ions, which can contaminate the environment and damage the human health. Therefore, the precise detection of trace Hg concentration is particularly important. Herein, gold nanoparticles-enhanced silver-coated hollow fiber (HF) surface plasmon resonance (SPR) sensor was developed for the highly sensitive detection of Hg ions.

In recent years, the increase in industrial and agricultural activities has heightened concerns about heavy metal pollution. In vitro conditions are an important tool for determining the optimum and toxic amounts of heavy metals and for evaluating plant species, especially those that are difficult to germinate, against unfavorable soil conditions. Therefore, this study evaluated heavy metal toxicity by applying different Hg (0.

With mercury pollution causes serious threats to ecosystems and human health because of its extreme toxicity and bioaccumulation, the development of efficient removal technologies has become an urgent environmental priority. This study introduces a novel adsorbent thiazolo[5,4-d]thiazole conjugated microporous polymer (TzTzCMP) for efficient Hg(II) removal from wastewater. TzTzCMP synthesized via condensation of dithiocarbamate and triformyl-phenol, exhibits a coral-like porous structure with a high specific surface area of 436.

Adsorption is a promising technique with significant potential for water purification. In this context, the present study examines the adsorption efficiency of poly(6-(ethoxybenzothiazole acrylamide) (PEBTA) in removing high-valent metal ions from aqueous environments, such as Th(IV), As(V), and Hg(II). Structural and chemical characterization of PEBTA is carried out by FT-IR, H-NMR, C-NMR, TGA, SEM, and EDAX.

High-performance effective and precise detection of Hg possesses great significance for ensuring environmental, food safety and public health, but still a great challenge. Here, efficient fabrication of NS-doped carbon dots (NS-CDs) were achieved and applied as fluorescent probe for cascade sensing Hg and BSA. NS-CDs emitted green emission at 500 nm under 355 nm excitation.
