“…Chemical sensors have a wide applicability and can be used for the recognition of neutral and charged species. These outcomes came combined with the development of supramolecular chemistry, [169] resulting in different physical and chemical properties, specially related to selenium and tellurium elements [170,171] . In this sense, Caltagirone and co‐workers have prepared a selenourea derivative to act as a colorimetric and/or fluorescent anion‐sensor (Scheme 40).…”

This review article deals with organic synthesis from the perspective of selenium-77 nuclear magnetic resonance (NMR) spectroscopy. Different types of organic reactions are briefly discussed, incorporating mechanism aspects through 77 Se NMR observable intermediates and byproducts. The 77 Se NMR experiments are demonstrated in terms of structural characterization and new insights for organic reactions. The ability to visualize different molecules in a reaction mixture provides a facile and versatile route for the development of synthetic organoselenium compounds. Thus, the review describes the strategies accomplished mainly in the past five years in the syntheses and applications of the organoselenium compounds, focusing on 77 Se NMR spectroscopy.

Cost metrics can include levelized costs of water treatment as well as individual cost components, such capital or operations and maintenance (O&M) costs. Energy PerformanceEnergy performance metrics can include the total energy requirements of the water treatment process, the type of energy required (e.g., thermal vs. electricity), embedded energy in chemicals and materials, and the degree to which alternative energy resources are utilized. Water Treatment PerformanceWater treatment performance metrics can include the percent removal of various contaminants of concern and the percent recovery of water from the treatment train. Human Health and Environment ExternalitiesExternality metrics can include air emissions, greenhouse gas emissions, waste streams, societal and health impacts, land-use impacts. Process AdaptabilityProcess adaptability metrics can include the ability to incorporate variable input water qualities, the ability to incorporate variable input water quantity flows, the ability to produce variable output water quality, and the ability to operate flexibly in response to variable energy inputs.

“…Because of its toxic nature and bioaccumulation via food chains in the adjacent biome, the high Se levels in water must be monitored and treated properly. The (United states environmental protection agency) USEPA lay down a maximum contaminant level (MCL) of 50 µg Se (total Se) per L in drinking water (Zhang et al, 2020a , b , c ). Due to their high mobility and bioavailability, the two oxidized Se types, (Se(VI) and (Se(IV), are normally soluble and more harmful to biological systems (Zhou et al, 2019 ).…”

Selenium (Se) is an essential metalloid and is categorized as emerging anthropogenic contaminant released to the environment. The rise of Se release into the environment has raised concern about its bioaccumulation, toxicity, and potential to cause serious damages to aquatic and terrestrial ecosystem. Therefore, it is extremely important to monitor Se level in environment on a regular basis. Understanding Se release, anthropogenic sources, and environmental behavior is critical for developing an effective Se containment strategy. The ongoing efforts of Se remediation have mostly emphasized monitoring and remediation as an independent topics of research. However, our paper has integrated both by explaining the attributes of monitoring on effective scale followed by a candid review of widespread technological options available with specific focus on Se removal from environmental media. Another novel approach demonstrated in the article is the presentation of an overwhelming evidence of limitations that various researchers are confronted with to overcome achieving effective remediation. Furthermore, we followed a holistic approach to discuss ways to remediate Se for cleaner environment especially related to introducing weak magnetic field for ZVI reactivity enhancement. We linked this phenomenal process to electrokinetics and presented convincing facts in support of Se remediation, which has led to emerge ‘membrane technology’, as another viable option for remediation. Hence, an interesting, innovative and future oriented review is presented, which will undoubtedly seek attention from global researchers.
