    Abstract: Assessing the quality of traditional African medicines (tradimedicines) requires the development of methods for the overall analysis of the pharmacologically active and/or chemically characteristic constituents present. The chromatographic profile of phytochemical metabolites is an important tool for the quality control of these drugs. Obtaining a ... Show More

    Abstract: This paper describes a procedure for the determination of thallium by differential pulse anodic stripping voltammetry (DPASV) using a mercury film deposited on glassy carbon as the working electrode. The procedure has been optimized using experimental design methodology. The following results were obtained: deposition potential: -1000 mV, depositio... Show More
