Determination of Zinc, Cadmium, Lead, Copper and Silver Using a Carbon Paste Electrode and a Screen Printed Electrode Modified with Chromium(III) Oxide
In this study, the preparation and electrochemical application of a chromium(III) oxide modified carbon paste electrode (Cr-CPE) and a screen printed electrode (SPE), made from the same material and optimized for the simple, ...
Amalgam electrode-based electrochemical detector for on-site direct determination of cadmium(II) and lead(II) from soils
Toxic metal contamination of the environment is a global issue. In this paper, we present a low-cost and rapid production of amalgam electrodes used for determination of Cd(II) and Pb(II) in environmental samples (soils ...
Electrochemical Microsensors for the Detection of Cadmium(II) and Lead(II) Ions in Plants
Routine determination of trace metals in complex media is still a difficult task for many analytical instruments. The aim of this work was to compare three electro-chemical instruments [a standard potentiostat (Autolab), ...
Gold Nanoparticles-Cysteine-Multiwall Carbon Nanotube Modified Electrode for Heavy Metal Ions Detection
The environmental contamination by heavy metals is one of the global problems that disturb the ecological balance. A platform for the simultaneous electrochemical detection of trace heavy metal ions has been developed based ...
Sunflower Plants as Bioindicators of Environmental Pollution with Lead (II) Ions
In this study, the influence of lead (II) ions on sunflower growth and biochemistry was investigated from various points of view. Sunflower plants were treated with 0, 10, 50, 100 and/or 500 mu M Pb-EDTA for eight days. ...
Application of the Enzymatic Electrochemical Biosensors for Monitoring Non-Competitive Inhibition of Enzyme Activity by Heavy Metals
The inhibition effect of the selected heavy metals (Ag+, Cd2+, Cu2+, and Hg2+) on glucose oxidase (GOx) enzyme from Aspergillus niger (EC 18.104.22.168.) was studied using a new amperometric biosensor with an electrochemical ...
