     in this present paper, the copper-coated magnetic carbon (ccmc) was fabricated by pre-deposition of ferric ferrous oxides onto carbon particles and followed by the chemical deposition of copper. galvanic couples composed of zero-valent iron and copper-coated magnetic carbon (fe0/ccmc) were employed for the treatment of simulative wastewater containing p-nitrophenol (pnp). under the optimized conditions such as magnetic induction intensity, mass ratio of fe0/ccmc and initial ph, it was found that the degradation rate of pnp greatly increased due to the enhancement of the internal microelectrolysis of fe0/ccmc couples in the intermittent magnetic field. in addition, the half-life value of cod of simulative wastewater containing pnp was used as a parameter to evaluate the degradation efficiency of pnp by interior microelectrolysis of zero-valent iron (fe0), zero-valent iron/carbon (fe0/c), zero-valent iron/magnetic carbon (fe0/mc) and zero-valent iron/copper-coated magnetic carbon (fe0/ccmc), respectively. it showed that the degradation efficiency of pnp by interior microelectrolysis of fe0/ccmc was the highest among them. the degradation process could be described as a pseudo-first-order model and liquid chromatography–mass spectrometer (lc–ms) analysis showed that amino-phenol was an intermediate during the degradation of pnp.
