ABSTRACT Mercury ions (Hg 2+ ) seriously harm the central nervous system of humans, leading to brain damage and even heart failure death. Therefore, effective detection Hg in water quality has become an urgent research field. It is very important develop economically efficient fluorescent sensors achieve rapid sensitive . high fluorescence quantum yield carbon dots (CDs) with amide group were prepared. The process preparing CDs was regulated by multiple key factors (carbon source, proportion, time), best performance selected. comprehensively characterized, including performance, surface structure, phase, morphological characteristics. endows ability act as both donors acceptors for hydrogen bonding, forming complexes metal ions, thus making them suitable worth noting that can quickly detect within 1 min, there a good linear relationship ranges 0.001–200 μM 200–500 μM. limit UC‐CDs 8.2 nM. This study provides sensor fast reaction, excellent sensitivity, selectivity water.

The synthesis of NS-CDs was carried out using precursors from Cavendish Banana Peel and l-Cysteine as a dopant with the solvothermal method. characteristics were analyzed through High-resolution transmission electron microscopy (HR-TEM), X-ray diffractometer (XRD), energy dispersive X-Ray spectroscopy (EDX), Fluorescence spectrometer (XRF), photoelectron (XPS), UV–Visible spectrophotometer, Photoluminescence, Atomic Absorption Spectroscopy (AAS). Based on HR-TEM analysis, exhibited spherical shape (dot) an average particle size 2.03 nm. Meanwhile, based XRD characterization, showed graphite carbon according to diffraction patterns (002) (001). Subsequently, XRF EDX testing revealed that elemental composition dominated by (C), nitrogen (N), Sulphur (S), oxygen (O). Furthermore, in XPS testing, S2p, C1s, N1s, O1s peaks correlated around 64 eV, 285 400 531 eV respectively. In UV–Vis gap found be 5.71 (NS-CDs 3:1), 5.46 5.25 1:1), 5.51 1:2), 5.56 1:3).
