Tetrabromobisphenol A (TBBPA) is a popular material and offers quality fire-retarding material, brominated poly-epoxy-phenolic resin, at low cost. 2,6-Dibromophenol (2,6-DBP) is detected as a degradation product of TBBPA-contaminated water. Residual material in the manufacturing industry is probably the cause of the ppb level contamination, and fire-retarding plastic materials scrap is building up in world-wide. 2,6-DBP is characterized by the odor of disinfectant at low threshold by the human sense of smell, as low as the ppt class. In this work, we aim at the remediation of water pollution. Degradation of 2,6-DBP is studied by a coaxial dielectric barrier discharge with multiple working gases.
