The main component of TV shell was confi rmed, which is HIPS doped with PBDEs. The effects of temperature on degradation of HIPS and removal of PBDEs were discussed through thermogravimetric analysis, it is concluded that 280c is the optimal temperature point for removing PBDEs and protecting HIPS, and the removed effi ciency of PBDEs is about 83%. Mass transfer law of removal of PBDEs of TV shell was also studied. And according to the mass transfer theory, the ideal mass transfer model was established, which refl ects the basic characteristics of fl ame retardants removal exactly. By comparing with the experimental data, the results showed t
