Description A new colorimetric method for the determination of ethylene dibromide in
microquantities is reported. The method consists in (I) hydrolysing ethylene
dibromide at 90°C for 30 min with sodium monoethanolamine taken in excess of the
theoretical requirement and (2) treating the unreacted sodium monoethanolamine
with 1% p-nitrobenzenediazonium fluoborate solution to form a blood red coloured
complex; the optical density of the complex is measured at 510 nm, the region of
maximum absorption. By this method, ethylene dibromide can be estimated in
microquantities (up to 10 ,ug/ml) with an accuracy of ±10%.
