TL;DR: In this article, the use of differential pulse polarography, differential pulse voltammetry and adsorptive stripping voltammetric for the determination of trace amounts of selected nitrated polycyclic aromatic hydrocarbons (1-nitropyrene, 9-nitroanthracene, 2-nitroprene and 2,7-dinitrofluorene were chosen as model substances) was studied.

TL;DR: In this paper, the differential equation of linear diffusion was solved with the boundary condition controlled by the chemical kinetics, and the result obtained gives the rate of the consecutive reaction consisting of the diffusion process and the electrode process.
Abstract: The differential equation of linear diffusion was solved with the boundary condition controlled by the chemical kinetics. The result obtained gives the rate of the consecutive reaction consisting of the diffusion process and the electrode process. This theory can explain the course of the polarographic current-time curve very well.

TL;DR: In this paper, a micro working electrode and a reference electrode using semiconductor processes for electrochemical detection of heavy-metal-ions were fabricated and the stripping voltammetry using mercury electrodes has been used to detect trace concentration of ions.
Abstract: We have fabricated micro working electrodes and a reference electrode using semiconductor processes for electrochemical detection of heavy-metal-ions. The stripping voltammetry using mercury electrodes has been used to detect trace concentration of ions. If the applied potential to the mercury electrode is negative than the standard redox potentials of heavy-metal-ions, then the ions existing in liquid are amalgamated into the mercury electrode. After this preconcentration process for a few minutes, the potential is increased linearly in the apposite direction and the amalgamated metals are stripped out into solution. By measuring the current peaks while sweeping the voltage, we can find heavy-metal-ions and their concentrations dissolved in the liquid.

TL;DR: Using differential-pulse voltammetry, the drug yielded a well-defined voltammetric response in Britton-Robinson buffer solution, pH 4.0 at -1.286 V, and the method was successfully applied for the analysis of meloxicam in the tablet dosage form.
