Hexavalent chromium (chromium VI) is a common form of chromium, a metallic element, that can exist in natural waters in concentrations ranging from 1 to 100 ug/L.
WHY IS IT IMPORTANT?
Chromium VI is an important water quality parameter to monitor in drinking water as it is a known carcinogen for humans. Chromium VI is released in small amounts from rocks and soils, however it can also be released from anthropogenic sources such as industrial pollution. The EPA currently has a maximum contaminant level (MCL) for total chromium species (Cr(III) plus Cr(VI)) of 100 µg/L (0.1 mg/L).
For industrial wastewater, chromium VI ends up in water as a result of several processes in metal processing, electroplating and cement industries. Due to it’s high toxicity it requires removal from the wastewater and safe disposal. Continuous monitoring can help optimize treatment, reduce levels at the source when possible and ensure regulatory requirements are met.
HOW WE MEASURE HEXAVALENT CHROMIUM
Real Tech’s innovative multiple wavelength sensors utilize patent-pending and proprietary technology for superior measurement performance across multiple wavelengths of light using UV LEDs. Many compounds absorb light in the UV-VIS spectrum including hexavalent chromium (chromium (VI), Cr (VI), or chromium 6). Compounds that may interfere with chromium VI measurement are compensated for using additional reference wavelengths. Real Tech offers both bypass (CRL series) and probe (CRA-X series) Chromium VI sensor options to allow the right selection for our clients needs. Multiple path length options are also available to ensure our clients have the detection range that meets their monitoring demands.
Real Tech has the solutions to help our clients get the information they need, when they need it. Discover our real-time chromium VI monitoring solutions here.
