Untersuchung von Thallium in Rohstoff-und Umweltprobenults. Therefore, different decomposition techniques with the subsequent separation procedures are presented. The analytical deter-mination was performed by atomic absorption spectro-photometry and inverse voltammetry, according to concen-tration. Experiences gathered with these methods are reported.
