• Description:
  Three highly selective procedures for the determination of formaldehyde (50000) and formaldehyde releasing compounds are introduced. In all cases xanthylium cationic or dicationic dyes are formed. The procedures have sensitivities approximately two and one half times that of the chromotropic-acid (148254) method. A sensitive thermochromic blue spot test for formaldehyde with 6-amino- 1-naphthol-3-sulfonic-acid (87025) or 6-anilino-1-naphthol-3- sulfonic-acid is described, and nine different methods for the determination of formaldehyde are compared. The interference of formaldehyde releasing compounds is discussed. Description provided by NIOSH
