Highly sensitive fluorescent imidazolium-based sensors for nanomolar detection of explosive picric acid in aqueous medium

Waste PET as a Reactant for Lanthanide MOF Synthesis and Application in Sensing of Picric Acid

“…In spite of these issues, TNP has been widely used in the dye industry and for leather. TNP can easily cause contamination of the soil and ground water [24][25][26]. Although high-explosive detection methods are highly selective and accurate, they suffer from shortcomings including the expense, the need for sophisticated instruments, that they are time-consuming, which limits their use for daily application [27].…”

Selective Fluorescent Turn‐Off Detection of Picric Acid Using a Novel Tripodal Supramolecular Triazole‐Trindane‐Based Receptor

“…The explosive compounds possessing nitro functional groups like picric acid (PA) and trinitrotoluene (TNT) are commonly used, but the use of PA is comparatively high because of its more explosive ability than the TNT . Despite the explosive nature, PA is also used in various dye industries, leather, making pharmaceuticals products, fireworks and rocket fuels . The properties of good water solubility, moderate vapour pressure and low degradation ability of PA resulted in the easy contamination of environmental soil and water, and therefore PA entered human body to cause several health problems.…”

An efficient and sensitive chemosensor based on salicylhydrazide for naked-eye and fluorescent detection of Zn2+

“…The demand for chemosensors that are selective and sensitive for specic target ion is continuously increasing. Numerous sensitive detection methods for metal ion recognition have been widely used in the eld of analytical chemistry, biology and environmental processes, [15][16][17][18] such as mass spectrometry, atomic absorption spectroscopy and high performance liquid chromatography. However, these methods are laborious and require the use of complex equipment.…”
