Assaying Thallium Determination Method. Previous Next Thallium is a rare metal, found in small quantities in some varieties of iron and copper pyrites, and in some lithia micas. It resembles lead in appearance.pounds resemble the salts of the alkalies in some respects and, in others, those of the heavy metals. It is detected by the green colour which its salts impart to the flame
There are two main methods of removing both radioactive and stable isotopes of thallium from humans. First known was to use Prussian blue, which is a solid ion exchange material, which absorbs thallium. Up to 20 g per day of Prussian blue is fed by mouth to the person, and it passes through their digestive systemes out in the stool.

Thallium is a chemical element with the symbol Tl and atomic number 81. It is a gray post transition metal that is not found free in nature. When isolated, thallium resembles tin, but discolors when exposed to air. Chemists William Crookes and Claude Auguste Lamy discovered thallium independently in 1861, in residues of sulfuric acid production. Both used the newly developed method of flame spectroscopy, in which thallium produces a notable green spectral line. Thallium, from Greek θαλλός, thallós, meaning a
Thallium is widely distributed in nature, but the only minerals rich in the element are crooksite and lorandite. It is also found in copper pyrites and lead and zinc ores it is recovered during the processing of these ores, the method of recovery depending on the source. Thallium is used in low melting alloys with other metals andpounds.
