| Abstract: | Based on the special molccular structure of surfactant paramagnctic material used as magnetic nucleus wascoated with two layers of surfactant inculding an inner layer and an outer layer and an outer layer Magnetic reagent can combine with activated carbon due to adsorption of hydrophilic raclical of the outer surfactant layer so activated carbon has magnetism Theeffects of magnetic reagent dosage. pH and activator upon the magnetic susceptibility of activated carbon were studied.Conceming the optimal conditions. MR-20 is the best magnetic reagent. Concentration of CaCl2 is 0.02M and pH1.8-2.4The physical properties of magnetic activated carbon vary with the types dosage and magnetizing condition of magneticreagent. |
