A simple and facile method of synthesis of silver nanoparticles is developed in this work. The silver nanoparticles are prepared by chemical reduction method using sodium citrate as a reducing agent. The average size, size distribution, morphology, composition and structure of particles were determined by scanning electron microscopy (SEM), Transmission Electron Microscopy (TEM), Inductively coupled plasma mass spectrometry (ICP-MS), and UV/Visible absorption spectrophotometry. We found that the silver nanoparticles with size about of 20 nm and good distribution are prepared without using any surfactant or stabilizer. The antibacterial activity is surveyed with six different concentrations in 6 hours. We found that all bacterials in the shrimp effluent have been removal completely after 6 hours contact with Ag NPs 0,1 mg/L. The result demonstrated that systhesized Ag NPs in this study is obtained high treatment bacterials in the shrimp effluent effect. The results of this work suggest that the good properties of Ag NPs are synthesized by this facile method and the high anti-bacterial activities are also determined in the wastewater of shrimp pond, obtaining standard drain out the river and reuse.
