Abstract The solubility of thallium sulfide in 1 M NaClO 4 at 25° ranges between 10 5 M as a function of pH and total sulfide concentration. Soluble thallium was analysed by anodic stripping using the hanging mercury drop electrode. The following complexes have been identified and their stability constants calculated: Tl 2 (HS) + , Tl(HS), Tl 2 (OH) (HS) 2 2−and Tl 2 (OH) 2 (HS) 2 2− .
