摘要
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.
The characteristics of Pb2+ removal from aqueous solutions by phosphatic ores in different conditions had been studied and the reaction mechanisms had been discussed. The data indicate that the Pb2+ sorption property of phosphatic ore depended on its mineral composition and structure. The high Pb2+ sorption capacity of the ore is in accordance with its high fluorapatite content, and the high CO content,low crystallinity of the fluorapatite. The P - rich phosphate rock may be applied to treat Pb2+ pollution
