摘要:
以3-氨丙基乙氧基硅烷（APTES）为改性剂，成功地合成改性凹凸棒石(ATP)，并研究了其对水溶液中Pb(II)的吸附性能。主要采取SEM、XRD、BET、FTIR和TGA对改性前后ATP的物理结构和化学组成进行测试分析；通过单因素静态实验，探讨了吸附时间、吸附剂用量、温度、Pb(II)初始浓度等因素对改性ATP吸附Pb(II)性能的影响。结果表明吸附时间80min，吸附剂用量0.35 mg•L-1，温度35 ℃，pH为6，初始浓度100mg•L-1时平衡吸附量为241.4 mg•g-1。
Abstract:
With APTES as a modifer, the modified ATP was successfully prepared. And the adsorption of Pb(II) from aqueous solution by modified ATP was studied. The physical structure and chemical composition of raw ATP, purified ATP and modified ATP were characterized by SEM、XRD、BET、FTIR and TGA, respectively. The effects of contact time、the dosage of adsorbent、temperature and initial concentration on the adsorption property for Pb(II) were investigated through single factor static experments. The results showed that the equilibrium adsorption capacity of Pb(II) was 241.4mg•g-1 under the following conditions:contact time 80 min、the dosage of adsorbent 0.35g•L-1、temperature 35ºc、 ph 6 and initial concentration 100mg•L-1.
