Phototurbidimetric determination of microquantities of hexabromobutene-2 in industrial waste waters
Hexabromobutene-2 (HBB-2), C/sub 6/H/sub 2/Br/sub 6/ containing 90.1% bromine is being widely used to reduce the flammability of foam polystyrene; it is one of the components of waste water from this industry. The Fujivaro reaction has been applied to determine HBB-2 to determine HBB-2 in wash waters. However, working with pyridine and aniline is difficult and requires special conditions. It has been found that microquantities of HBB-2 in water can also be determined phototurbidimetrically since stable colloidal solutions are formed by the addition of sulfuric acid to aqueous solutions of HBB-2. The authors have developed a method for the determination of HBB-2 in industrial waste waters. Sodium formate is added to the samples to be analyzed in order to eliminate the interference of elemental bromine. Ethanol, chloride, bromide, and iodide ions do not interfere in the determination; neither does elemental bromine when present in concentrations not exceeding 20 mg/dm/sup 3/.
