Thallium is a chemical element; it has symbol Tl and atomic number 81. It is a silvery-white post-transition metal that is not found free in nature. When isolated, thallium resembles tin, but …

Dec 15, 2018 · Thallium is a rare element in the Earth, with an average crustal abundance of 0.7 ppm (Shaw, 1952, Heinrichs et al., 1980, Wedepohl, 1995) and is primarily found as a trace …

Tl+ is concentrated in residual soils and sediments (less certainty.) Tl+ enters later phases in igneous rocks due to its large size. This table compares the known valid mineral species listed …

In the case of thallium (Tl), it has been shown that in natural Tl-rich sulfide deposits and those found in mining areas, Tl can be trapped by Tl-jarosite (Tl-rich iron sulfate) and dorallcharite …

Thallium, a soft, bluish-gray, malleable heavy metal, was discovered by Sir William Crookes in 1861 while he was making spectroscopic determinations for tellurium on residues from a …

Thallium is commercially produced as a byproduct of refining heavy metal sulfide ores. The primary use of thallium is in the electronics industry, but it also has application in the …

Apr 17, 2015 · We investigated the speciation and extractability of Tl in soil developed from mineralized carbonate rock. Total Tl concentrations in topsoil (0–20 cm) of 100–1000 mg/kg …

This overview presents the updated physicochemical characteristics of thallium and its stable isotopes (205Tl/203Tl) in the context of their occurrence and fate in abiotic and biotic systems.
