Strychnine Sulphate

The determination of hydrogen peroxide at concentrations higher than those normally covered in polarography was studied with various electrodes. The diffusion current was found to increase linearly with the peroxide concentration up to 0.15% with the dropping mercury electrode and up to nearly 1% with a fixed platinum microelectrode. Under these conditions the limiting current was about 10 times greater than that usually observed. Although the solutions were supersaturated with oxygen, traces of strychnine sulphate were sufficient to suppress all maxima.

Dropping Mercury Electrode

A study of the two polarographic prewaves of the Ni(II)–thiourea system has been made. The results were analysed by determining Koutecky's parameter from the ratio of the limiting current of the prewaves and the main wave. This parameter is considered an experimental rate constant and the influence of different variables on its value was analyzed. An electrochemical study of the prewaves was also made. Two formal mechanisms to explain both prewaves are proposed. Key words: polarographic prewaves, electrochemical kinetics, reaction mechanisms.
