Application: | Potassium tetrathionate (K2S4O6) can be used as an energy source for the batch culture of Acidithiobacillus caldus. K2S4O6 can be used as an additive (pit prevent agent) to prepare an electrolyte composition for electroplating of Cu-Sn alloy. It can also be used to study the adsorption competition of lead and sulfur on nickel in acidic aqueous media. K2S4O6 is preferred over other sulfur species as it is an acid-stable source of S and does not produce a large quantity of H2S. |
General description: | Potassium tetrathionate is a sulfuric acid dimerformed by a disulfide linkage. It is widely used in the field of microbiology as aningredient for tetrathionate broth. |
