| 摘 要： | 详细地研究了硼在水合氧化锆吸附剂上的吸附行为。研究结果表明，水合氧化锆的吸硼速率较快，２ｈ可完全达平衡，且吸附可用Ｆｒｅｕｎｄｌｉｃｈ等温吸附线很好地拟合。被吸附的硼易被碱液洗脱，通过水合氧化锆上硼的“吸附－脱附循环”研究，表明该吸附剂的吸附性能好，再生能力强，循环使用寿命长，是一种很有价值的高效脱硼吸附剂。

| Abstract: | In this paper, behavior of boron adsorption on hydrous zirconium oxide adsorbent is studied in detail. It shows that the adsorption rate of boron on the adsorbent is high and the eqlibrium can be reached Within two hours. Moreover, boron adsorption follows Freundlich isotherm equation with a good straight line relationship. Adsorbed boron can be easily desorbed by alkali solution. The adsorption-desorption cycle of boron on the adsorbent is further examined, the result shows that the adsorbent has a better adsorption ability, a stronger regeneration ability and a longer cycle-life, therefore the hydrous zirconium oxide possesses a good developing value for the removal of boron from seawater. |
