Abstract:
This work presents a new method for generating a BrCl solution, starting from the commercially available dibromodimethylhydantoin (DBDMH). This method is notable due to the straightforward, safe and clean performance, being based on a simple addition of DBDMH into aqueous HCl. The whole procedure is finished in about 20 min. An advantage of the proposed method is avoiding of tedious reagents pre-cleaning by prolonged thermal treatment, spontaneous overheating and excessive vapor evolution. The resulting BrCl stabilization reagent is low enough in mercury content to be directly used in trace mercury analysis. A thorough study of the BrCl solutions prepared by this method showed that they conform in all respects to US EPA 1631e/2002 requirements.
