Chronopotentiometry at Varying Current Density with the Use of Current Controlled Dropping Mercury Electrode

Electroreduction of Some Diazine and Triazine Pesticides at the Dropping Mercury Electrode

Electroanalytical methods enable determination of electroactive species in nonhomogeneous systems, as limiting currents are little affected by the presence of solid and colloidal particles. An example of such applications of electrochemical methods are studies of binding of toxic substances, such as pesticides, on slightly soluble polymers, such as lignin. To successfully apply polarographic me...

Prediction of the Current Density at an Electrode at Which Multiple Electrode Reactions Occur under Potentiostatic Control

Electrochemical Kinetic Measurements and Metal Speciation with the Vibrating Dropping Mercury Electrode

The vibrating dropping mercury ele·ctrode (VDME) is applied to the characterization of ionic species and to electroanalytical measurements of metal ion concentrations in water samples strongly polluted with different kinds of surface active substances (SAS). The Cd2+ /CdNTAsystem in citrate buffer solution at pH = 6 was chosen as a model for the effect of a preceeddng homogeneous chemical react...

The Study of Electrochemical Reduction of Ni(II)- Amino Acid and Pyrimidines Complexes at Dropping Mercury Electrode

The electrochemical studies of Ni(II) complexes with alanine, leucine, glycine, adenine, cytocine, uracil at constant ionic strength (μ=0.1) in aqueous alcohol, DMF and formamide mixture have been investigated. The reduction was diffusion controlled as evidenced from linear plots of id against h . The mechanism of reduction and effect of solvent, concentration, pH have been studied. Slope value...

A general formulation both for stow elec- Irode reactions at the dropping mercury electrode and for kinetic polarographic cur-

Irode reactions at the dropping mercury electrode and for kinetic polarographic currents was found and the solution derived with the help of dimensionless quantities. The interpolation formula for average kinetic polarographic currents is inagreement with experimentally found dependences on relevant parameters, and it has a form very similar to the older approximate equations of Brdi~kaand Wies...
