-- A selective and rapid colorimetric procedure has been developed for determining formaldehyde content in aqueous extracts of cellulose film.
-- Metrological characteristics of the procedure in the formaldehyde concentration range 0.02–0.16 mg/liter have been found. The detection limit is 0.016 mg/liter of formaldehyde.
