摘　　要：采用流变相前驱物法制备锰锌铁氧体磁性催化剂,将自制的磁性催化剂用于催化降解废弃涤棉混纺物。通过熔点、傅立叶变换红外光谱、质谱对降解产物进行表征。结果表明,降解产物主要为对苯二甲酸二乙二醇酯(BHET)单体,最高回收率达82%,回收的棉纤维物理力学性能没有破坏,催化剂可回收重复利用多次。Mn-Zn ferrite magnetic catalyst was synthesized by the rheological phase reaction. Home-made catalyst was used for catalytic degradation of cotton-polyester blended fabric. The melting point,flourier transform infrared spectrometer(FTIR), ion mass spectrometry were adopted to characterize and analyze the degraded products. The results show that BHET is degradation products of polyester. The highest recovery rate of BHET is up to 82%. The mechanical and physical properties of reclaimed cotton fiber are not damaged. The catalystcan be repeatedly used.
