Abstract
Formaldehyde, after in situ derivatization with Girard's reagent T, wa s determined in aqueous solution using differential-pulse polarography . A;single peak was obtained at pH 8 when using 1 x 10(-3) mol l(-1) N H4Cl/NH3 as the supporting electrolyte. The minimum detectable concent ration of formaldehyde was 1.3 x 10(-6) mol l(-1). As little as 0.2 mu g of formaldehyde can be determined accurately by using this method. In addition, acetaldehyde was proven to not interfere with the formald ehyde determination.
