Abstract: Sulfidation in cooperation with magnetic field was used to remove arsenic from simulative waste water. The processes were studied by chemical analysis, conductivity gauge, potentials difference, X-ray diffraction and scanning electron microscopy. The results showed that the sedimentation rate of As2S3 and the utilization ratio of sulfide agent is increased in the magnetic field, the flocculation and filtration rate are improved also. There are some changes in the structure of the water and the energy state of the particles in the water in magnetic field.
