Summary
Graphitic carbon nitride efficiently removes dyes from water within seconds. Silver nanoparticles on this material enable sensitive detection of pharmaceutical products using SERS, aiding water purification and drug analysis.
Area of Science:
- Materials Science
- Environmental Chemistry
- Analytical Chemistry
Background:
- Scarcity of drinking water necessitates rapid methods for removing water contaminants like dyes.
- Sensing pharmaceutical products in water bodies is crucial for environmental and health monitoring.
Purpose of the Study:
- To prepare graphitic carbon nitride (g-C3N4) for efficient water contaminant adsorption.
- To synthesize silver nanoparticles decorated g-C3N4 for pharmaceutical sensing using SERS.
- To evaluate the adsorption and sensing capabilities of the developed materials.
Main Methods:
- Preparation of graphitic carbon nitride (g-C3N4).
- Decoration of g-C3N4 with silver nanoparticles.
- Adsorption studies using methylene blue as a model dye.
- In-situ surface-enhanced Raman scattering (SERS) for drug sensing.
Main Results:
- g-C3N4 demonstrated rapid adsorption (∼5s) of halogenated organic dyes.
- Dye adsorption efficacy reached nearly 80% with good linearity (R² = 0.9731).
- Ag nanoparticles decorated g-C3N4 showed good sensing performance for acetaminophen drug via SERS.
Conclusions:
- Graphitic carbon nitride is a highly effective adsorbent for water dye removal.
- Silver nanoparticles decorated g-C3N4 offer a promising platform for real-time SERS-based pharmaceutical sensing.
- This approach facilitates the development of high-performance sensors for water quality monitoring.
