Hexavalent chromium or Cr(VI) is a toxic form of chromium which can cause severe health effects to workers, including lung cancer. Chromium compounds are added to paints and primers to provide corrosion protection and to create specific colors.

Trivalent Chromium Technology. In most chrome plating baths the ions suspended in solution are hexavalent (Cr+6). Our new "green" trivalent chrome plating bath uses trivalent (Cr+3) ions for metal deposition. Hexavalent chromium is a known carcinogen which poses health risks to those who use this material in chrome plating. Hexavalent ...

Introduction. The presence of heavy metal ions in surface water continues to be the most pervasive environmental issues of present time (Hotton and Symon, 1986; Nriagu, 1988).Chromium is one of the contaminants, which exists in hexavalent and trivalent forms.

Batch experiments were performed to investigate optimum condition for removal of hexavalent chromium(Cr(VI)) from groundwater by nanoscale zero valent iron/Cu. With the decrease of pH value, the decrease of the initial concentration of Cr(VI) and the increase of temperature, the removal efficiency of Cr(VI) increases.

Hexavalent chromium, also known as chromium 6 (Cr6), is the toxic form of the metal chromium. While some less toxic forms of chromium occur naturally in the environment (soil, rocks, dust, plants, and animals), Cr6 is mainly produced by industrial processes.

Chromium extensively used in tanning, electroplating, and textile dyeing is of particular environmental concern in the aquatic system, which normally exists in two stable states: trivalent chromium (Cr(III)) and hexavalent chromium (Cr(VI)).

Hexavalent Chromium SERDP and ESTCP efforts have encompassed a range of issues related to Cr(VI). The major areas of research and demonstrations include the following:
