Abstract:
Background:Calcium Channel Blockers (CCBs) are widely used in the treatment of cardiovascular and ischemic heart diseases in recent years. They treat arrhythmias by reducing cardiac cycle contraction and also benefit ischemic heart diseases. Electroanalytical methods are very powerful analytical methods used in the pharmaceutical industry because of the determination of therapeutic agents and/or their metabolites in clinical samples at extremely low concentrations (10-50 ng/ml). The purpose of this review is to gather electroanalytical methods used for the determination of calcium channel bloc

Abstract:
Anodic stripping voltammetry, a classical electroanalytical method has been optimized to analyze trace Pd (II) in tailings. The authors identified the registration conditions in the determination of the analytical signal Pd (II): the composition of background electrolyte and the electrolysis potential. The electroanalytical approaches with an unmodified carbon electrode were used. The use of stripping voltammetry applied to the assessment of the palladium content in geological objects was demonstrated.

In this work the gallium and bismuth film plating in situ and ex situ processes were investigated. The metal film plating conditions for determination of heavy metals in water samples were optimized. When depositing Bi films on glassy carbon electrode it was found, that the addition of Br-1 changes the BiFE morphology making it more uniform and forming crystalline aggregates. The reoxidation peak of Bi was shifted to more negative potentials showing the electrocatalytic effect of bromide for the bismuth film.

There was proposed method for the determination of manganese in drinking water by inverse voltammetry using a mercury film electrode. The determination of manganese in drinking water does not need chemical treatment of a sample. Optimal detection conditions: accumulation potential of -1.75 V, accumulation time 5-30 s, anodic dissolution is performed using square wave voltammetry. Manganese accumulation by the detection limit of 30 seconds is about 0.4 mg l-1, and the relative standard deviations of the working range of concentrations do not exceed 0.10.
