英文摘要: Based on the special structure of surfactants, a magnetic reagent was prepared by using a paramagnetic material as magnetic nucleus and coating with two layers of surfactants. The activated carbon was magnetized because a magnetic reagent can be combined with activated carbon based on the hydrophilic reaction of the outer surfactant layer with surface of the activated carbon. The effect of the magnetic reagent dosage, pH value and activator upon the magnetic susceptiblity of the magnetic activated carbon were studied. The optimal condition was determined: MR-20 was used as the magnetic reagent under a pH of 1.8 similar to 2.4, with the existarce of activator at 60 degreesC. The physical properties of the magnetic activated carbon varied with the magnetic susceptiblity of the carbon.
