Potassium thiosulfate (KTS) is a water-soluble compound used primarily as a fertilizer, providing both potassium and sulfur to plants. It's a neutral to basic, chloride-free, clear liquid solution, often blended with other fertilizers like urea. KTS is known for its ability to delay nitrification, reducing nitrous oxide emissions and improving nitrogen-use efficiency in soils.

Industrial Uses

1. Agrochemicals

  • Potassium: KTS is a readily available source of potassium, a crucial nutrient for various plant functions, including regulating water uptake, enzyme activation, and protein synthesis. 
  • Sulfur: It also provides sulfur, another essential nutrient for plant growth, particularly in the production of amino acids, proteins, and chlorophyll.

2. Water Treatment

  • The Reaction: Potassium thiosulfate reacts with chlorine (hypochlorite) in a chemical reaction that neutralizes the chlorine, effectively removing it from the water. This reaction is similar to how sodium thiosulfate reacts with chlorine.

3. Metal Treatment

  • Lixiviant: Potassium thiosulfate (K₂S₂O₃) is primarily used in metal treatment as a lixiviant for leaching precious metals, particularly gold, from ores and electronic waste. It's a cyanide-free alternative, offering reduced environmental risk, high selectivity, and lower corrosivity.
