Abstract

Formaldehyde, after in situ derivatization with Girard's reagent T, was determined in aqueous solution using differential-pulse polarography. A single peak was obtained at pH 8 when using 1 × 10^-3 mol l ^-1 NH₄Cl/NH₃ as the supporting electrolyte. The minimum detectable concentration of formaldehyde was 1.3 × 10 ^-6 mol l^-1. As little as 0.2 μg of formaldehyde can be determined accurately by using this method. In addition, acetaldehyde was proven to not interfere with the formaldehyde determination.
