Abstract

Modification of adsorbent with nanomaterials has become a widely adopted method to improve their surface morphology and adsorption capacity. In the present study, Bauhinia tomentosa seedpod (BTSP) was modified with unary NiO nanoparticle to form NiO-BTSP adsorbent for the removal of methylene blue (MB) from water. The functional, optical, and morphological properties of the synthesized adsorbent was characterized by Fourier transform infrared spectroscopy, UV-Vis Spectroscopy, Energy Dispersive X-Ray, and Scanning electron microscopy. Results showed formation of agglomerated particles with pore spaces that were loaded with dye molecules after adsorption. Adsorption studies revealed formation of multiple layers of dye molecules on the adsorbent at an optimum pH of 12 and maximum monolayer capacity of 357.14 mg/g. Kinetics modeling of the adsorption data showed that adsorption occurred through chemical interaction between the adsorbent and dye molecules to reach equilibrium in 60 min. Desorption experiments using different organic and inorganic acids and bases further revealed the reusability potential of the adsorbent with optimal regeneration obtained using as low as 0.01 M acetic acid.

nio -生物质微复合材料用于植物修复废水中亚甲基蓝。

利用纳米材料对吸附剂进行改性已成为一种广泛采用的改善吸附剂表面形貌和吸附能力的方法。本研究以单纳米NiO对毛毛紫荆（Bauhinia tomentosa）种子荚（BTSP）进行改性，制备了NiO-BTSP吸附剂，用于去除水中亚甲基蓝（MB）。利用傅里叶变换红外光谱、紫外可见光谱、能量色散x射线和扫描电镜对合成吸附剂的功能、光学和形态性质进行了表征。结果表明，吸附后形成的球状颗粒具有吸附染料分子的孔洞。吸附研究表明，在最佳pH值为12，最大单层容量为357.14 mg/g时，吸附剂上可形成多层染料分子。对吸附数据的动力学建模表明，吸附通过吸附剂与染料分子的化学相互作用在60 min内达到平衡。不同有机酸和无机酸、碱的解吸实验进一步揭示了吸附剂的重复利用潜力，在低浓度为0.01 M的乙酸条件下获得最佳再生效果。

期刊介绍： The International Journal of Phytoremediation (IJP) is the first journal devoted to the publication of laboratory and field research describing the use of plant systems to solve environmental problems by enabling the remediation of soil, water, and air quality and by restoring ecosystem services in managed landscapes. Traditional phytoremediation has largely focused on soil and groundwater clean-up of hazardous contaminants. Phytotechnology expands this umbrella to include many of the natural resource management challenges we face in cities, on farms, and other landscapes more integrated with daily public activities. Wetlands that treat wastewater, rain gardens that treat stormwater, poplar tree plantings that contain pollutants, urban tree canopies that treat air pollution, and specialized plants that treat decommissioned mine sites are just a few examples of phytotechnologies.
