摘　　要：研究合成了一种对磷酸根离子具有高度选择性的新型离子液体负载树脂,并用于富集湿法磷酸中磷酸,考察了磷酸质量浓度、吸附时间、温度对磷酸根吸附量的影响。结果表明:在优化吸附条件下,磷酸根吸附量可提升至307 mg/g;该树脂能有效避免磷灰石浸出液中诸多阳离子的影响,显著提高湿法磷酸纯度,且具有一定的环保和经济效益。A new ionic liquid loaded resin with high selectivity for phosphate ions was synthesized and used to enrich phosphoric acid in wet process phosphoric acid.The effects of phosphoric acid mass concentration,adsorption time and temperature on phosphoric acid adsorption were investigated.The results show that the adsorption capacity of phosphoric acid can be increased to 307 mg/g under optimized adsorption conditions.The resin can effectively avoid the influence of many cations in apatite leaching solution,significantly improve the purity of wet-process phosphoric acid,and has certain environmental protection and economic benefits.
