description The invention discloses a compound of lanthanum molybdate and ferromagnetic materials and application of preparation and adsorption phosphorus removal, belonging to the technical field of phosphorus removal from sewage and wastewater. The preparation method of the composite comprises the following steps of: dispersing ferromagnetic materials in water, adding lanthanum salt, fully mixing, adding ammonium molybdate, sodium molybdate or potassium molybdate, adjusting the pH to 8-10, and performing coprecipitation reaction to obtain lanthanum molybdate. The reaction system is placed in a reactionkettle and reacts under the condition of 180 DEG C or more to obtain a composite of lanthanum molybdate and ferromagnetic materials. According to the composite disclosed by the invention, the selective adsorption function of lanthanum molybdate on phosphate radicals is utilized, and the superparamagnetism of ferromagnetic ore is utilized at the same time, so that the adsorbent can be separated andregenerated under the con
