A chemical reaction of PBDEs was implemented using the polyethylene glycols (PEGs) and KOH, along with different reaction conditions such as temperatures and times. Removal efficiencies of PBDEs before and after chemical reaction were examined by difference of concentration. PBDEs was not removed at lower temperatures of 25 and . However, under the increased temperature, removal efficiency of PBDEs in -xylene was gradually increased, showing completely removal of PBDEs containing 5-6 bromines on biphenyl frame. When increasing the reaction conditions to 4 hours and , removal efficiency of PBDEs reached almost 100%. In studying the reaction of PEGs with PBDEs, it confirmed that the PBDEs led to less brominated by PEGs through a stepwise process with the successive elimination of bromines.
