| 摘 要： | 采用间歇法研究了天然磷灰石、合成磷灰石、改性磷灰石去除废水中重金属离子的特性，主要研究了改性磷灰石的去除特性。结果表明，在室温与常压下，对废水中重金属离子的去除顺序为Ｐｂ＾２＋〉Ｚｎ＾２＋〉Ｃｕ＾２＋，去除机理为吸附与离子产换的协同作用。改性磷灰石去除效果理想，成本代，制作工艺简单。

| Abstract: | Characteristics of heavy metal removal from waste water by using the natural apatite,synthesis apatite and upgraded apatite have been studied with the batch method.The removal characteristics of the upgraded apatite is the focus of the study.The results show that at the ambient temperature and the standard pressure, the order of heavy metal removal from waste water is as follows: Pb~ 2 >Zn~ 2 >Cu~ 2 .The removal mechanism is the synergism of adsorption and ion exchange. With the upgraded apatite, the removal effect is ideal, the cost is low and the process is simple. |
