The present study investigates the effective removal of phosphate in sewage wastewater using silver nano-cs films (Ag NP’s-CS). The ecofriendly prepared silver nanoparticles (Ag NP’s) embedded in chitosan of around 8–10 nm was synthesized using non-toxic-green method. The interaction of Ag NP’s-CS film and phosphate was studied using UV-Vis technique. Ag NP’s-CS film exhibit more than 95% phosphate reduction in 5 min and close to 100% in 10 min. High-resolution scanning electron microscopy, X-ray diffraction, UV-Vis and Fourier transform spectrometry were used to characterize the AgNP’s-CS film. The film has been shown to be effective for the detection and the removal of phosphates from natural wastes and wastewaters within the response time of 2-3 seconds.
