Preparation and adsorption mechanism of NHFO@pumice for ammonia nitrogen

Funds: National Key Research and Development Program (2019YFC0408504); Provincial Natural Science Research Project of Higher Education in Anhui Province (KJ2019ZD52; KJ2020A0466; KJ2021A0619); Introduction of Talents and Doctoral Program of Anhui Jianzhu University (2019QDZ64; 2019QDZ60)
  • 摘要: 蜂巢石与纳米水合氧化铁(NHFO)是水处理中常用的吸附剂,研究采用共沉淀法将NHFO负载到蜂巢石上,探究其对氨氮的吸附性能及机制。实验探究了初始氨氮浓度、初始pH值及共存阳离子(H+、Na+、K+、Mg2+)对NHFO@蜂巢石吸附氨氮的影响。采用SEM-EDS、XRD等手段表征NHFO@蜂巢石的形貌及结构。结果显示:氨氮初始浓度为20 mg/L,pH值7左右时具有较好的吸附能力;共存离子对氨氮的吸附有抑制作用,抑制强度为H+>Na+>K+>Mg2+。SEM-EDS、XRD、FTIR等表征手段证实了NHFO成功负载在蜂巢石上,吸附过程符合Langmuir吸附等温线(R2=0.9886)和准二级动力学模型(R2=0.9969)。研究表明:氨氮主要通过羟基和NH4+的静电作用、离子交换和孔隙吸附共同实现的。该研究为吸附法处理氨氮废水提供了理论依据。
