Determination of Formaldehyde in Water-Borne Coatings by HPLC

Abstract:

A method for determination of formaldehyde in water-borne coatings by high-performance liquid chromatographic was proposed. Ultrasonic water extraction method was used instead of the traditional steam distillation method can be more rapid and efficient extraction of target, filtered and derivatived with DNPH. The extract was separated by C18 column with an elution composed of acetonitrile and water, and detected at 352nm. The detection limit was 0.1mg/L. The method showed good linear correlation, R² was 0.9997 at the range of 0.1mg/L ~ 20 mg/L. Recovery was 95% ～105%. This method is simple, effective and sensitive.
