Scope
This standard specifies the test method for total chromium, hexavalent chromium, and trivalent chromium in recycled water—voltammetric polarography.
This standard is applicable to the determination of the mass concentration of chromium in recycled water, with a measurement range of 1.0 μg/L to 100 μg/L. This standard is also applicable to the determination of total chromium, hexavalent chromium, and trivalent chromium in drinking water, surface water, and wastewater.
