The method for preparing the compound adsorbent material of MgO/ charcoal using lemon dregs and magnesium slag one-step method

The invention belongs to technical field of adsorption material preparation, the method for specially preparing the compound adsorbent material of MgO/ charcoal using lemon dregs and magnesium slag one-step method.Method includes the following steps: 1) weigh, a certain amount of lemon dregs are added in magnesium slag solution and constant temperature is stirred to moisture evaporating completely, to form uniform lemon magnesium slag；2) the lemon magnesium slag of formation is placed in N 2 Atmosphere furnace high-temperature process obtains MgO/ carbon composite.The MgO/ carbon composite that this method is prepared has many advantages, such as that light weight, absorption property are good, adsorption efficiency is high, good with other inorganic compound composite performances.The MgO/ carbon composite of formation is a kind of strong adsorption capacity, high-efficient, long service life and low-cost water treatment agent, breaches inorganic material in the industrial applications of water-treatment technology field.
