Abstract A flow-injection system is proposed for the rapid determination of trace amounts of
formaldehyde based on its inhibition of the Brilliant Green—sulphite reaction at pH 7.
Formaldehyde in the range 40–3000 ng ml− 1 can be determined at a rate of 35±5 samples
h− 1. The limit of detection was 20 ng ml− 1. The relative standard deviation for the
determination of 1 μg ml− 1 formaldehyde was 0.2%. The method was applied to the
determination of formaldehyde in melamine—formaldehyde resin and chemical industrial ...
