Quantitative determination of potassium ions by flame photometry in the drug “Panangin”

Abstract

Annotation. Determination of the quantitative content of potassium ions by flame photometry in the drug “Panangin”® produced by “Gedeon Richter” Plc (Hungary) and study the accuracy of this method by calculating the measurement error. The drug “Panangin”® was used in the form of film-coated tablets. The filtrate was quantified with potassium ions on a BWB-XP flame photometer using a propane-butane mixture. Calibration of the device was performed using solutions of potassium chloride of the following concentrations: 1,00, 10,00, 25,00 and 50,00 mg / l, the reference solution was deionized water. The quantitative content of potassium ions was measured using flame photometry. The proposed method of quantitative determination of K+ ions in the drug “Panangin”® belongs to the analytical and pharmaceutical chemistry and is intended for quality control of drugs containing potassium. According to the results of the study, we can see that the method of flame photometry gives reproducible results.
