Descripción general

Potassium iodide is an inorganic sodium salt. It is used as a source of iodide in organic synthesis. In the presence of oxidizing agents, it iodinates aromatic hydrocarbons and organothallium compounds. It is also used as a reagent for the cleavage of some ethers in the presence of acid.

Aplicación

Potassium iodide can be used as a reducing agent for the reduction of graphene oxide in the presence of hydrochloric acid. It is also used as a dopant in the preparation of solid polymer electrolytes for energy devices.

Características y beneficios

  • Increased efficiency – Eliminates time and effort of loosening hardened powders      
  • Safety – Eliminates tools of force used to break up clumps
  • Ecology – Reduces waste as it does not stick to the packaging
  • Economy – Faster preparation and solvation increase productivity and reduce costs      
  • Assured Quality – Excellent, expert-tested quality with no anti-caking agents     
  • Flexible volumes – Available from research amounts to scale-up quantities

Are protein oxidative stress markers [thiols, advanced oxidation protein products (AOPP), protein carbonyls and nitrates/nitrites] in perioperative peritoneal fluid higher in women with histologically proven endometriosis when compared with endometriosis-free controls? Protein oxidative stress markers are significantly increased in peritoneal

Bentonite, which is used as an engineered barrier in geological repositories, is ineffective for sorbing anionic radionuclides because of its negatively charged surface. This study modified raw bentonite using a cationic surfactant (i.e., hexadecyltrimethylammonium [HDTMA]-Br) to improve its sorption capability
