Green Synthesis Of Silver NPS As A Highly Sensitive Biosensor To Detect The Mercury Inside The Soil Sample Of SORAN Area
Through this study, the silver nanoparticles (Ag NPs) was green synthesized via a simple, economic and eco-friendly method using the aqueous extract of the roots of Euphorbia condylocarpa as capping and stabilizing agent and without any stabilizer or surfactant agent. The green synthesized silver NPs was characterized using the Uv-vis, FT-IR, XRD, SEM, EDS and Mapping analytical techniques then employed as a nanosensor for detecting the mercury inside the soil samples of Soran city. The reaction between Ag NPs and mercury (II) or mercury containing ions was introduced as a novel colorimetric process for the specified recognition and monitoring of mercury containing compounds in soil samples of different parts of Soran city from Iraqi Kurdistan. The biologically synthesized sensor is brown in color due to the intense SPR absorption band around 430 to 450 nm. In the presence of Hg2+, the mentioned SPR signal was gradually disappeared indicating the presence of mercury inside the samples.
