TRACER DIFFUSION OF THALLIUM IN THALLIUM AMALGAMS
Canadian Journal of Chemistry, 1964The tracer diffusion coefficient of thallium in thallium amalgams was measured at 25 °C by the capillary-reservoir technique. The values of 105D in cm2 s−1 at 0.0075, 0.0713, 0.1610, 0.2004, 0.2858, 0.3460, 0.3868, 0.4158 mole fraction thallium were 0.98, 0.85, 0.71, 0.62, 0.47, 0.41, 0.38, 0.39 with an average standard deviation of 0.016 × 10−5 cm2 s−

Thallium in Wein — Spurenelement-Vinogramm des Thalliums
Zeitschrift für Lebensmittel-Untersuchung und -Forschung, 1984Das Ultra-Spurenelement Thallium ist regelmasig in geringsten Gehalten in Wein enthalten, in Rotwein durchschnittlich 0,2 μg Tl/l, mehr als in Weisweinen mit durchschnittlich 0,1 μg Tl/l. Uber Herkunft und Verhalten solcher geringsten Thallium-Gehalte konnen einige Hinweise aus den zusatzlichen Untersuchungen (Boden, Standort, Dungemittel, Einflus der ...

Pediatrics, 1958
Fourteen children with thallium poisoning are described. Alopecia and neurologic symptoms dominate the clinical picture. In the absence of alopecia, the diagnosis depends upon a high degree of suspicion in regard to any child presenting bizarre neurologic complaints with acute onset.

Spectrophotometric determination of thallium as thallium tetriodide
Analytica Chimica Acta, 1962Abstract Iodide ions react with thallic ions at pH 2–8 to form a complex iodide, which is suitable for the spectrophotometric determination of thallium. The reaction has a sensitivity of 0.05 μg Tl per cm2 for log I 0 I = 0.001 and obeys Beer's law up to 40 p.p.m. Optimum conditions for the reaction have been established.

Thallium(II) in the chemically induced thallium(I)-Thallium(III) exchange
Journal of Radioanalytical Chemistry, 1976Abstract The rate of the electron exchange between thallium(I) and thallium(III) induced by iron(II) has been measured at various concentrations of Tl(I), Tl(III), and Fe(II).204Tl tracer, initially in the Tl(I) state, was used. Exchange induced by the separation method was less than 0.01%.

Thallium Bromide Semiconductor Radiation Detectors with Thallium Contacts
2017 IEEE Nuclear Science Symposium and Medical Imaging Conference (NSS/MIC), 2017Thallium bromide (TlBr) is a wide bandgap, compound semiconductor with high gamma-ray stopping power and promising physical properties. The electro-migration of Br-ions towards anode and their reaction with the contact have been long known to adversely influence the lifetime of TlBr devices. We report on the performance of TlBr devices with Tl contacts

Publisher Summary This chapter discusses the spectrophotometric determination of thallium from silicate rock material, using brilliant green. It is necessary to separate thallium from interfering elements, such as antimony, tin, mercury, cadmium, chromium, and tungsten. The chapter describes the solvent extraction of thallic bromide into diethyl ether
