Abstract
A magnetic magnesium-manganese layered double metal oxide composite and preparation and application. A soluble magnesium salt and a soluble manganese salt are dissolved in water to obtain a magnesium-manganese salt complex liquid; and a soluble carbonate and a soluble hydroxide are dissolved in water to obtain a carbonate-hydroxide complex liquid; a ferroferric oxide powder is added to the carbonate-hydroxide complex liquid, and then ethanol is added for ultrasonic dispersion to obtain a dispersion liquid; then the magnesium-manganese salt complex liquid is added for aging, centrifuging, washing, drying, grinding for sieving, and calcinating at 250-550° C. to obtain a magnetic magnesium-manganese layered double metal oxide composite. The composite of the present invention has relatively strong magnetism to Cd removal, and is featured by high adsorption efficiency, rapid adsorption rate and stability. Moreover, the composite can not only immobilize Cd efficiently, but also can be separated and recycled by magnet.
