The invention discloses a method for removing anions in phosphogypsum slag field leaching solution. The method comprises the steps of using phosphogypsum to prepare hydroxyapatite magnetic nanowires, and then using hydrophobic ionic liquid to modify the hydroxyapatite magnetic nanowires. After drying, it is used to remove the anions in the phosphogypsum slag field leaching solution; the method of the invention has a removal rate of anions higher than 80%, which realizes the improvement of the water quality of the phosphogypsum slag field leaching liquid, and is also the phosphogypsum slag field leaching liquid. The treatment provides technical support and reduces the risk of harm to the ecological environment from the leachate; the method has low cost, simple operation, and at the same time, the raw material is phosphogypsum, which achieves the purpose of treating waste with waste. |
