摘要
采用自制的氧化锆负载树脂氟离子吸附剂对含氟水进行处理,考察了吸附剂吸附时间、溶液pH等吸附条件对其吸附性能的影响。结果表明,该吸附剂有较大的吸附容量,对氟离子的吸附在室温下符合Langmuir等温吸附,而且吸附速率快,吸附动力学符合拟二级动力学方程,并且脱附效果好,再生能力强,是一种具有广泛应用前景的新型氟离子吸附剂。
Adsorbent loaded with ZrO ·nH2O was used for the adsorption of fluorideion. The effect of adsorption time and pH value of solution on the adsorption properties was investigated. Experimental results showed that the adsorbent loaded with ZrO·nH2O had good adsorption properties for the fluoride ion. In the room temperature the adsorbent loaded with ZrO·nH2O had a high adsorption capacity and quick speed for fluorideion,the adsorption process fitted the Langmuir isothermal adsorption; at the same time, the speed of the adsorption process followed the pseudo-second-order kinetics equation. And it had high selectivity for desorption. It show economic and useful of make use of waste material to wastewater treatment.
