Potassium dichromate has been used to prepare:
  • An oxidant mixture along with sulfuric acid that is employed during the estimation of polychlorinated biphenyls.
  • Golgi-Cox solution.
  • Cr(VI) stock solution for assessing the performance of octadecyltrimethylammonium bromide-montmorillonite (ODTMA-MMT) micelle clay complex in removing Cr(VI) from aqueous solutions.

General description

Potassium dichromate, a toxic hexavalent chromium compound, is a strong oxidizing agent. Its nephrotoxicity in humans and animals has been studied. Its crystalline structure has been analyzed. Its ability to induce genetic and DNA methylation alteration has been assessed in Brassica napus L. plants.
