Measurement of Chromium(VI) by Ion Selective Electrode (CAT#: STEM-ACT-0112-WXH)

Introduction

Chromium (VI) is an oxidation state of the element chromium. Other common oxidation states of chromium include 0 (the metallic element chromium), and III (the state in which chromium is found in nature. Chromium (III) compounds are dealt with elsewhere in the NPI). Hexavalent chromium compounds (VI) include ammonium dichromate, barium chromate, calcium chromate, chromium trioxide, lead chromate, sodium dichromate, strontium chromate, potassium chromate, potassium dichromate, sodium chromate, and zinc chromate.
Chromium VI compounds are classified as Carcinogenic Category 1A, which means they are a proven cause of cancer in humans. Chromium VI exposure occurs through breathing it in, ingestion via food or water, or direct contact with the skin.
