Abstract

Objectives: The present study is focused on the determination of thallium (I) ions in homeopathic drugs.Methods: The determination was carried out using the Differential Pulse Anodic Stripping Voltammetry (DPASV) technique coupled with the flow-injection measuring system (FIA-DPASV).Results: The thallium content was analyzed in two commercial homeopathic preparations (Thallium aceticum 5CH and 9CH), which include two different concentrations of thallium. It was established, that the mean concentration of thallium in the 5CH drug was at 6.67 ng L-1 in the administered daily dose, whereas in case of 9CH the value was at 2.1 ng L-1 of thallium.Conclusion: The obtained results indicate that the application of the studied homeopathic drugs for medical purposes is not associated with any hazards in terms of possible toxicity due to thallium content.
