Determination of microquantities of hexabromocyclododecane in air

The authors develop and present a simple and accessible method of determining microquantities of hexabromocyclododecane (HBCD) from the air to be analyzed, and they remove elementary bromine. The analytical procedure is described and tables present the results of the experiments. They found that acetone and ethanol did not interfere with the determination of HBCD in air. It was established that in the method of collection of air samples described, hydrogen bromide and elementary bromide are not retained by silica gel and also do not interfere with the determination of HBCD.
