Abstract The hydrothermal synthesis is presented of copper-doped carbon dots (Cu-CDs) from citric acid, urea, and copper chloride, resulting in blue-fluorescent particles with stable emission at 438 nm when excited 340 nm. Through comprehensive spectroscopic microscopic characterization (FTIR, XPS, UV, HRTEM), the Cu-CDs demonstrated remarkable stability across varying pH levels, ionic strengths, temperatures, UV exposure. Notably, exhibit ultra-sensitive selective detection hexavalent chromium [Cr(VI)] ions aqueous environments driven by fluorescence quenching. system showed a robust linear response to Cr(VI) 0–80 µM range, an impressive limit (LOD) 0.186 µM, significantly lower than WHO’s permissible 0.96 µM. These findings position as effective tool for environmental monitoring water safety applications. Graphical

Safe drinking water and a clean living environment are essential for good health. However, the extensive growing use of hazardous chemicals, particularly carcinogenic dyes like methylene blue, methyl orange, rhodamine B, malachite green, in both domestic industrial settings, has led to scarcity potable environmental challenges. This trend poses serious threat human society, sustainable global development, marine ecosystems. Consequently, researchers exploring more advanced methods beyond traditional wastewater treatment address removal or degradation these toxic dyes. Conventional approaches often inadequate effectively removing from wastewater. In this study, we investigated bimetallic metal-organic frameworks (BMOFs) as solution limitations. BMOFs demonstrated outstanding dye capabilities due their multifunctionality, stability, large surface area, adjustable pore size, recyclability. review provides comprehensive overview research on using BMOFs, including synthesis methods, types dyes, processes involved removal, such adsorption. Finally, discusses future potential emerging opportunities treatment.
