Cyanides
CN-
Applications
- Drinking water
- Industrial wastewater
- Municipal wastewater
- Surface water
Description
The determination ranges of the cyanide analyzer vary from trace μg/L to 10 mg/L CN- using the (optional) internal dilution module.
Method
The cyanide ions present in the sample reacts with the chloramine-T and pyridine/barbituric acid reagents. The absorbance intensity is proportional to the cyanide concentration in the sample and is measured at 572 nm.
