Catecholamine drugs are aromatic vic-diols in which both the 3or 4-position is unsubstituted and these positions are not sterically blocked. Epinephrine(EP) or adrenaline(I) and norepinephrine(NE) or noradrenaline (II) are catecholamine drugs that are widely used in the treatment of allergic emergencies, status asthmatics, bronchial asthma, ventricular bradycardia, cardiac arrest, glaucoma, and...

conclusions this easily fabricated electrode together with the fast and sensitive sw voltammetry was successfully applied for the determination of concentration of atz at trace levels, in different water samples. results the results revealed that decrease in peak current was proportional to atz concentration over the range of 5-75 ng/ml. the limit of detection (lod) and limit of quantification ...

A new method of indirect determination of Cu(2+) was developed based on square-wave voltammetry by the oxidation of iodide in organic solvent at the liquid/liquid (L/L) interface. The limit of detection for the determination of Cu(2+) in this method was found to be 5 x 10(-4) mol/L, and the concentration ranged up to 1 x 10(-2) mol/L gave a linear limiting current versus concentration response....

A novel indirect electrochemical protocol for the electroanalytical detection of phenols is presented for the first time. This methodology is demonstrated with the indirect determination of the target analytes phenol, 2-chlorophenol, 4-chlorophenol and 2,4-dichlorophenol through an electrochemically adapted optical protocol. This electrochemical adaptation allows the determination of the above ...
