Abstract
In this project, silver deposited on graphitic carbon nitride-silicon carbide-polyglutamic acid (Ag/g-C 3 N 4 /SiC/PGA) nanomaterials was chemically fabricated. The Ag/g-C 3 N 4 /SiC/PGA nano probe analyzed via UV–vis, TEM, EDS, DLS, and zetasizer analyzer. The prepared nanomaterials was applied for colorimetric detection of sulfide ions as toxic material. The particle size and zeta amount of Ag/g-C 3 N 4 /SiC/PGA was −28.00 mV and 30 nm, respectively. The detection of S 2− ions was conducted by probe with variation in colour with response time of 60 s. The absorbance showed good linearity with S 2− concentrations. The LOD of S 2− ions by Ag/g-C 3 N 4 /SiC/PGA was 0.15 nM. The Ag/g-C 3 N 4 /SiC/PGA catalyst was used to degradation of ampicillin (AMP). The photo-degradation amount of AMP in 50 min was 95.62% under visible light irradiation. The Ag/g-C 3 N 4 /SiC/PGA nanoparticles demonstrated the highest antibacterial efficiencies. • The silver doped on graphitic carbon nitride-silicon carbide-polyglutamic acid was chemically fabricated. • The LOD of S 2− ions by Ag/g-C 3 N 4 /SiC/PGA was 0.15 nM. • The AMP degradation amount of Ag/g-C 3 N 4 /SiC/PGA was 95.62% in 50 min. • The Ag/g-C 3 N 4 /SiC/PGA demonstrated the highest antibacterial efficiencies.
