An Electrochemical Sensor Based on Nickel Oxides Nanoparticle/ Graphene Composites for Electrochemical Detection of Epinephrine
The combination of graphene and nickel oxide nanoparticles yields nanostructured electrochemical sensor formed a novel kind of structurally uniform and electrocatalytic activity material. In cyclic voltammetry studies, in the presence of epinephrine, nickel oxide / graphene composite modified electrode shows a significantly higher current response for epinephrine oxidation. Based on differenti...
متن کاملDevelopment of Carbon Paste Electrode/EDTA/Polymer Sensor for Heavy Metals Detection
The method used to immobilize the polymer on the Disodium ethylenediamine tetraacetate (EDTA) modified carbon paste electrode (CPE/EDTA) has proved its effectiveness for the detection and chelation of heavy metals in aqueous solution. Its complex formation with Pb(II) was examined by square wave voltammetry and cyclic voltammetry. CPE/EDTA electrodes are predisposed to the phenomenon of dissolu...
متن کاملHeavy Metal Toxicity
Heavy metals are metallic elements which have a high atomic weight and a density much greater (at least 5 times) than water. There are more than 20 heavy metals, but four are of particular concern to human health: lead (Pb), cadmium (Cd), mercury (Hg), and inorganic arsenic (As). According to the U.S. Agency for Toxic Substances and Disease Registry. These four heavy metals are four of the top ...
متن کاملHeavy Metal Toxicity
In general, irritable health concern related to heavy metal (accumulation) might be mainly divided into 2 types, i.e. heavy metal poisoning caused by excessive extrinsic exposure and genetic disorders such as Wilson disease (as reviewed by Osredkar et al. in this issue). As for the former type, unlike the latter one, it can be said that the health damage spread with the development of the civil...
