Determination of Chromium (VI) (SM 3500-Cr B Method)

The SM 3500-Cr B method, which includes a test method for the determination of chromium, has been developed within the scope of the National Environmental Methods Index (NEMI).Migrants.

Chromium is an element used in alloys, electroplating and pigments. Chromate compounds are frequently added to the cooling water for corrosion control. The amount of chromium in the soil varies between 11-22 ppm. There is an average of 1 μg/L chromium in streams and 100 μg/L in groundwater. Chromium is mainly found in chromium-iron ore.

Chromium is found in natural waters as trivalent chromium. This chromium forms strong complexes with amines and is adsorbed by clay minerals. The most common forms of chromium in nature are tri- and hexavalent chromium. Chromium 6 occurs naturally in the environment, but is produced in large quantities as a by-product in industry. For example, for the production or storage of leather tanning and leather products. It is also found in treated lumber, paint, and other materials. It is added to paint and varnish and provides resistance to rust.

By the way, chromium is not necessary for plants, but is an essential trace element for animals. Hexavalent compounds are known to be carcinogenic and corrode tissue when inhaled.

In the tests and analyzes carried out in our institution, which has a wide range of technological equipment, trained and experienced staff and applies the most modern methods, national and international standards and legal regulations in force are complied with. Chromium (VI) determination (SM 3500-Cr B method) services are among the numerous tests performed in this context.
