Kinetics of the release of antimony trioxide from the backcoated textile preparation Ghanem, Raed Ahmad Kinetics Antimony trioxide Thermal degradation Photolytic segregation Hexabromocyclododecane Decabromodiphenyl ether (BDE 209) Segregation of antimony trioxide (ATO) from back-coated textiles was studied for two types of textile samples: A (ATO-Hexabromocyclododecane) and B (ATO-Decabromodiphenyl ether). Samples A was found to lose 5.3, 12, 28 and 39 %wt:wt of the amount of ATO originally present due to thermal ageing and UV exposure, respectively. Thermal ageing was performed at 25, 60 and 90 °C compared to 11.0, 17.3, 26.0 and 20.4 % wt:wt of ATO for sample B. The release follows first order kinetics with rate constants of 7.59×10-3, 1.89×10-2, 4.80×10-2 and 2.60×10-2 day-1, respectively, for type A and 9.20×10-3, 2.06×10-2, 4.10×10-2 and 3.83×10-2 day-1 for type B aged at 25, 60, 90 °C and UV exposure, respectively. Migration of ATO from the backcoated textile into simulated biological fluids was also studied for different type of samples under different ageing conditions using Head-over-Heels and contact blotting tests. The presence of biological fluids enhances the migration of ATO.
