AB  - Magnetic multi-walled carbon nanotubes (MWCNTs) were prepared to support Pd/Fe 
      nanoparticles, inhibit the aggregation and passivation, and achieve magnetic 
      separation to avoid the environmental risk of nanoparticles. Rapid adsorption of 
      initial contaminant, steady dechlorination, and gradual desorption of final 
      product was observed. The micromorphology, chemical structure, and components of 
      the nanohybrids were comprehensively characterized by a series of analysis 
      technologies, such as EDX, XRD, SEM, TEM, and XPS. The interactions between the 
      nanohybrids compositions were discussed according to the characterization and 
      experimental data. The whole insight of 2,4-dichlorophenol (2,4-DCP) adsorption- 
      dechlorination-desorption was studied in detail, including the pathways, 
      influence factors, dechlorination kinetics and selectivity. Weak acidity (pH=5.0 
      and 6.5) favored the 2,4-DCP removal. Satisfactory reactivity of the 
      Pd/Fe-Fe3O4@MWCNTs nanohybrids was observed in five consecutive runs, and 99.2%, 
      89.6%, 92.1%, 99.8%, and 99.9% of 2,4-DCP was removed, respectively. Most of the 
      final product (phenol) was steadily desorbed to the liquid phase, resulted in the 
      re-exposure of active sites on the nanohybrids and maintained a longer activity.
