Recently, the technique of magnetic separation has been used to dispose water, especially the waste water of low concentration. The technique of magnetic separation is that we segregate different materials with the power of magnetic field. In this study, using chitosan as raw materials, magnetic materials as the Cole, organically-linking technique was applied to produce magnetic microspheres. The study is mainly on the absorbent for Cr (VI) adsorption. The effect factors such as PH, the reaction time, the initial concentration and dosage temper...
