Emission and atomic absorption plasma spectrometry has been developed for the determination of potassium ion in the "OROX" preparation, solution for internal use 250. The developed method has been validated by the following parameters: specificity, linearity (the area of linear dependence is at potassium ion concentrations from 0.1552 to 0.2321 g/1.), Convergence and correctness (average percentage of composition opening 100.39%). The results obtained showed that the technique allows an objective assessment of the residual solvents in the drug.
