Identification of brominated flame retardants in polymeric materials by reversed-phase liquid chromatography with ultraviolet detection

Effects of humic acids and microorganisms on decabromodiphenyl ether, 4,4′-dibromodiphenyl ether and anthracene transportation in soil

“…An Agilent 1100 Series HPLC coupled with a diode array detector (DAD) was employed to measure BDE-209 and anthracene which were separated with a Supelco C18 column (Ace 5 C18, 150 × 4.6 mm, 5 m particles, Supelco, Bellefonte, PA, USA) at 30 °C [20,21]. A mixture of methyl alcohol and water was used as the mobile phase (95:5, 1.2 mL/min for BDE-209 and 80:20, 1.0 mL/min for anthracene).…”

Sequential reduction–oxidation for photocatalytic degradation of tetrabromobisphenol A: Kinetics and intermediates

“…As one of brominated flame retardants (BFRs), tetrabromobisphenol A {TBBPA; 4,4 -isopropylidenebis(2,6-dibromophenol)} is extensively used in fire safety treatment of paper, textiles, plastics, circuit boards, and in many other consumer goods [1][2][3], which consists of 60% of the total BFRs used world-wide [4]. Owing to its widespread use, TBBPA has led to its ubiquitous occurrence in various environmental matrices and biota.…”

Zn dust mediated reductive debromination of tetrabromobisphenol A (TBBPA)

“…Over the years, brominated flame retardants (BFRs), composed of several different chemicals of high production volume, have been widely used in polymeric substrates in order to improve their flame resistance. Thus, tetrabromobisphenol A [4,4 -isopropylidenebis(2,6-dibromophenol), TBBPA, 1] can be found as an additive in paper, textiles, plastics, carpets, upholstery, and epoxy resins, [3] utilized by the electronic industry in the production of printed circuit boards. World production of TBBPA stands at ca.…”
