Abstract: A new manganometric detn. of Tl+ in acid soln. and the presence of KBr at higher temp. is described. This is basically a bromometric titration which is in a soln. of H2SO4 or HCl with colored indicators or by using a potentiometer with a wide range of acidity. By this method it is possible to perform a potentiometric microdetn. of 1 mg. Tl with 0.004N KMnO4. In detg. Tl+ with Ce(SO4)2 the potentiometric indication is best in the presence of HCl. H2SO4 is disturbing even in the presence of KBr. 62 references.
