Background: Increasing awareness on the environmental impact of heavy metals has increased a considerable interest in the determination of metals in natural water bodies. The present paper describes the development and electrochemical application of carbon paste electrode modified with fibrous part of coconut shell for the determination of cadmium in water samples. Methods: Determination was ca...

An anodic stripping voltammetry instrument has been developed by ESA, Inc., Chelmsford, MA, in conjunction with CDC. This instrument provides a prompt, cost-effective technique to monitor lead exposures for pediatric screening. Although this instrument has only been used with children whose blood lead levels are significantly lower than in exposed adults, its capability to analyze blood quickly...

The Pb, Hg and As content of the muscle, gill and liver of marin organisms Otolithes rubber, Pampus argenteus, Parastromateus niger, Scomberomorus commerson, Onchorynchus mykiss were measured. Analysis of lead and arsenic was carried out by anodic stripping voltammetry method. Hg analysis was done spectrophotometrically. It was found that mercury concentration reaches to maximum in the gill of ...

This work demonstrates determination of lead (Pb) in surface water samples using a low-cost copper (Cu)-based electrochemical sensor. Heavy metals require careful monitoring due to their toxicity, yet current methods are too complex or bulky for point-of-care (POC) use. Electrochemistry offers a convenient alternative for metal determination, but the traditional electrodes, such as carbon or go...
