Abstract
Abstract Hydroxylamine ( −3 mol l −1 ) is quantified by ultraviolet spectrophotometry after reaction with an excess of formaldehyde in buffered solution at pH 12.2. The absorbance of the formaldoxime produced is measured at 218 nm (ϵ = 5480 l mol −1 cm −1 ) when hydroxylamine is alone but at 230 nm (ϵ = 3230 l mol −1 cm −1 ) when monochloramine is present.
