Thallium(I) sulfate inhibits the growth of plants by preventing germination. Tl 2 SO 4 is mostly used today as a source of Tl + in the research laboratory. It is a precursor to thallium(I) sulfide (Tl 2 S), which exhibits high electrical conductivity when exposed to infrared light.
Thallium poisoning is poisoning that is due to thallium and its compounds, ... The odorless and tasteless thallium sulfate was also used as rat poison and ant killer ...
The thallium is leached either by the use of an alkali or sulfuric acid from the material. The thallium is precipitated several times from the solution to remove impurities. At the end it is converted to thallium sulfate and the thallium is extracted by electrolysis on platinum or stainless steel plates. [43]
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]
001 surface has step growth of 4.6 Å, optical transmission bands at 250, 500 and 860 nm which are the same as nickel sulfate hexahydrate, but UV band transmits more. Heavy absorption 630-720 nm and 360-420 nm 3 density 2.596 g cm −3 .
Thallium compounds such as thallium sulfate have been used for impregnating wood and leather to kill fungal spores and bacteria, and for the protection of textiles from attack by moths. [24] Thallium sulfate has been used as a depilatory and in the treatment of venereal disease, skin fungal infections, and tuberculosis. [25]
This is the list of extremely hazardous substances defined in Section 302 of the U.S. Emergency Planning and Community Right-to-Know Act (42 U.S.C. § 11002).The list can be found as an appendix to 40 CFR 355. [1]
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]
