Description

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.

Application

Potassium dichromate has been used in experiments to determine the ability of MCM-41-supported nanoscale zero-valent iron (nZVI) sample to remove hexavalent chromium.
