Highly sensitive determination of heavy metals in water prior to and after remediation using Citrofortunella Microcarpa

Abstract A highly sensitive bismuth/silver nanoparticles/Nafion-modified screen-printed graphene electrode was fabricated and was utilized for the detection of trace lead (Pb) concentrations in river water samples prior to and after remediation using calamansi (Citrofortunella Microcarpa) rinds in d...
