The invention discloses a dephosphorization agent. The dephosphorization agent is an aqueous solution, contains calcium ions, acid ions, a dispersant and water, and the acid ions are selected from one or more of benzene methane sulfonic acid ions, dodecylbenzene sulfonic acid ions, 2-aminoethanesulfonic acid ions and sulfamic acid ions. The invention discloses a preparation method of the dephosphorization agent, and an application of the dephosphorization agent in vanadium extract liquid dephosphorization. By adopting the above technical scheme, the dephosphorization effect is guaranteed, and the vanadium loss is effectively reduced. The dephosphorization agent does not contain chloride ions, so the corrosion of vanadium extraction wastewater to equipment in the evaporative concentration running process can be avoided. When the dephosphorization agent is used to dephosphorize the vanadium extract liquid, the operation is simple.
