Thallium(I) sulfate is soluble in water and its toxic effects are derived from the thallium(I) cation. The mean lethal dose of thallium(I) sulfate for an adult is about 1 gram. Since thallium(I) sulfate is a simple powder with indistinctive properties, it can easily be mistaken for more innocuous chemicals.
2 to 5 days (with exceptions for heavy users who can test positive up to 4/6 weeks, and individuals with certain kidney disorders) up to 90 days: 2–10 days, heavy users or individuals with previous substance use 6/8 weeks Codeine: 2 to 3 days up to 90 days 1 to 4 days Cotinine (a breakdown product of nicotine) 2 to 4 days: up to 90 days: 2 to ...
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]
Tl 2 O 3 is metallic with high conductivity and is a degenerate n-type semiconductor which may have potential use in solar cells. [5] A method of producing Tl 2 O 3 by MOCVD is known. [6] Any practical use of thallium(III) oxide will always have to take account of thallium's poisonous nature. Contact with moisture and acids may form poisonous ...
Tl 2 S can be prepared from the elements or by precipitating the sulfide from a solution of thallium(I), e.g. the sulfate or nitrate. Thin films have been deposited, produced from a mixture of citratothallium complex and thiourea. Heating the film in nitrogen at 300°C converts all the product into Tl 2 S [4]
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.
Thallous acetate or thallium(I) acetate is a salt of thallium and acetate with the chemical formula TlCH 3 COO. It is used in microbiology as a selective growth medium . [ 3 ] It is poisonous.
A saturated solution of equal parts of thallium(I) formate (Tl(HCO 2)) and thallium(I) malonate (Tl(C 3 H 3 O 4)) in water is known as Clerici solution. It is a mobile, odorless liquid which changes from yellowish to colorless upon reducing the concentration of the thallium salts.
