Abstract
A novel green synthesis method was developed for sulfur-doped carbon dots (S-C-dots) using chicken egg white (CEW) and L-cysteine for the rapid and cost-effective detection of copper ions (Cu2+) in water. This one-pot, room-temperature, base-catalyzed approach eliminated the need for energy-intensive processes and purification steps, adhering to the principles of green chemistry. The synthesized S-C-dots were characterized using UV-Vis, FT-IR, fluorescence, EDS, XRD, and Z-potential analyses. Among the six samples tested, A060 demonstrated superior properties, achieving a detection limit of 3.3 ppb (52 nM) for Cu2+ in aqueous solutions. This study highlights the potential of S-C-dots as eco-friendly, accessible, and efficient tools for monitoring heavy metal contamination in drinking water, offering a promising solution to global water safety challenges.
期刊介绍:
Materials (ISSN 1996-1944) is an open access journal of related scientific research and technology development. It publishes reviews, regular research papers (articles) and short communications. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, there is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Materials provides a forum for publishing papers which advance the in-depth understanding of the relationship between the structure, the properties or the functions of all kinds of materials. Chemical syntheses, chemical structures and mechanical, chemical, electronic, magnetic and optical properties and various applications will be considered.
