Prussian blue, also known as potassium ferric hexacyanoferrate, is used as a medication to treat thallium poisoning or radioactive caesium poisoning. [1] [2] For thallium it may be used in addition to gastric lavage, activated charcoal, forced diuresis, and hemodialysis. [3] [4] It is given by mouth or nasogastric tube.
Thallium poisoning is poisoning that is due to thallium and its compounds, which are often highly toxic. [1] Contact with skin is dangerous and adequate ventilation should be provided when melting this metal. [2] Many thallium compounds are highly soluble in water and are readily absorbed through the skin. [3]
Thallium is malleable and sectile enough to be cut with a knife at room temperature. It has a metallic luster that, when exposed to air, quickly tarnishes to a bluish-gray tinge, resembling lead. It may be preserved by immersion in oil. A heavy layer of oxide builds up on thallium if left in air. In the presence of water, thallium hydroxide is ...
Thallium (81 Tl) has 41 isotopes with atomic masses that range from 176 to 216. 203 Tl and 205 Tl are the only stable isotopes and 204 Tl is the most stable radioisotope with a half-life of 3.78 years. 207 Tl, with a half-life of 4.77 minutes, has the longest half-life of naturally occurring Tl radioisotopes.
Thallium(I) oxide is the inorganic compound of thallium and oxygen with the formula Tl 2 O in which thallium is in its +1 oxidation state. It is black and produces a basic yellow solution of thallium(I) hydroxide (TlOH) when dissolved in water. It is formed by heating solid TlOH or Tl 2 CO 3 in the absence of air.
Similarly, thallium(I) aryl compounds require steric bulk for their isolation. [4] A well-known organothallium(I) species is thallium cyclopentadienide. It arises by treatment of thallium(I) salts, such as thallium sulfate, with cyclopentadiene. Thallium(I) cyclopentadienide adopts a zig-zag chain structure of cyclopentadienide and thallium. [5]
The overall thallium distribution profiles in the analyzed hairs suggested both chronic and acute thallium exposures that correlated well with the sequential presentation of a plethora of symptoms originally experienced by Zhu Ling. Aligning the time-resolved thallium peaks in the hair with her symptoms also provided clues on possible routes of ...
