摘要 Highly efficient silver halide nanoparticles (AgX, X = Cl, Br NP’s) were successfully synthesized by facile and template-free direct-precipitation method using potassium chloride, potassium bromide and silver nitrate as reactive sources. The as-prepared AgX NP’s were characterized by FTIR, thermogravimetric analysis, XRD, EDX and HRTEM. The antimicrobial susceptibilities against two Gram-positive bacteria (Bacillus cereus, Staphylococcus aureus) and four Gram-negative bacteria (Salmonella typhi, Escherichia coli, P. aeruginosa and Klebsiella pneumoniae) in addition to five fungi (Aspergillus flavus, A. carbonarus, Penicillium verrucosum, Fusarium verticelloides and A. niger) were tested by the disk diffusion technique. The antibacterial and antifungal results suggest that the prepared AgX NP’s show high activity against the tested organisms compared to tetracycline and Nystatin taken as standard drugs. As an application, the use of the prepared AgX NP’s as photo catalyst for the decontamination of malathion as VX chemical warfare agent (CWA) stimulant from water sample was extensively studied.
