Hydrazine and Monomethylhydrazine Measurement in Water and Air Using the Scan Method.
Abstract
The SCAN kit is a commercially available product used for analysis of hydrazine in boiler and waste water. The SCAN approach was tested and evaluated for its intended use and also for its adaptability for (1) measuring hydrazine in air and (2) measuring monomethyhydrazine (MMH) in both air and water. The technique involves aspiration of an aqueous sample (impinger or solid-sorbent extract) into an air-evacuated ampoule which contains a color-forming reagent. The intensity of the resulting color is read on a spectrophotometer. Test results indicated the SCAN method to be adequate for quick and easy field analysis of hydrazine in water to 0.01 mg/liter and in air to concentrations as low as 0.015 ppm, using a 15-liter air sample. MMH analysis required a color development time of 30 to 90 min which would interfere in certain field applications. MMH was measured at concentrations as low as 0.1 ppm, using 15-liter air samples.
