Abstract:Lead is environmental pollutant that even in low trace is harmful for human health and wildlife. In this study we presented a colorimetric method for determination of Pb 2+ in water by aggregation of silver nanoparticles capped citrate in the presence of deferoxamine as chelating agent. Silver nanoparticles were prepared by reduction of AgNO 3 with NaBH 4. In the presence of Pb 2+ , mixture of silver nanoparticles capped citrate and deferoxamine aggregated and color of solution changed from light yellow to vio… Show more
