对几种磷矿石在不同条件下除去水溶液中铅离子的特征进行了研究，并对相关反应机理进行了讨论，指出磷矿石的铅离子吸附性能决定于矿石的矿物成分及其结构特征，当磷矿石中氟磷灰石的含量较高、且其结晶程度较低而结构碳酸根含量较高时，磷矿石具有较高的铅离子吸附量.品位较高的磷块岩有望用于铅污染的治理.
Several kinds of phosphate rock were removed under different conditions to study the characteristics of lead ions in aqueous solution, and the related reaction mechanism was discussed. It was pointed out that the lead ion adsorption capacity of phosphate rock was determined by the mineral composition and structural characteristics of the ore, Phosphate rocks have higher Pb2 + adsorption capacity when phosphate rock has a higher content of fluorapatite and a lower degree of crystallinity and a higher carbonate content. Phosphorite with higher grade is expected to be used In the lead pollution control.
