Synergistic effects of anionic surfactants on adsorption of norfloxacin by magnetic biochar derived from furfural residue

Emerging pollutants—Part II: Treatment

“…With the development of society and the improvement of living standard, the production and consumption of PPCPs are increasing (Papageorgiou, Zioris, Danis, Bikiaris, & Lambropoulou, 2019). PPCPs can enter the environment with domestic wastewater, hospital wastewater, pharmaceutical wastewater, landfill leachate, and animal manure (Li, Gao, et al, 2019; Li, Li, et al, 2019; Li, Zhang, Zeng, et al, 2019; Li, Liu, Zhang, Li, et al, 2019; Li, Zhang, Xia, Wang, et al, 2019; Li, Zhang, Hu, et al, 2019; Li, Sun, Zhang, Feng, et al, 2019; Li, Wang, et al, 2019; Li, Yuan, Gao, Wang, & Sheng, 2019). At present, PPCPs of ng/L–μg/L level have been detected in water, soil, wastewater, and sludge of many countries and regions (Alonso, Demetrio, Capparelli, & Marino, 2019; Pérez‐Lemus, López‐Serna, Pérez‐Elvira, & Barrado, 2019).…”

“…According to the flow direction of wastewater, CWs can be mainly divided into surface flow, subsurface flow, and vertical flow CWs (Ghimire, Nandimandalam, Martinez‐Guerra, & Gude, 2019; Nivala et al, 2019; Phong Vo et al, 2019; Rabello, Teixeira, Gonçalves, & Salomão, 2019). The removal of EPs by CWs is mainly through the absorption and degradation (Li, Gao, et al, 2019; Li, Li, et al, 2019; Li, Zhang, Zeng, et al, 2019; Li, Liu, Zhang, Li, et al, 2019; Li, Zhang, Xia, Wang, et al, 2019; Li, Zhang, Hu, et al, 2019; Li, Sun, Zhang, Feng, et al, 2019; Li, Wang, et al, 2019; Li, Yuan, Gao, et al, 2019; Rabello et al, 2019). Adsorption is an important way to remove EPs, and the substrate, soil, and sediment of packed bed in CWs play major roles in adsorption (Nguyen, Chao, & Chen, 2019; Nguyen, Afzal, et al, 2019; Sardana, Cottrell, Soulsby, & Aziz, 2019; Zhao, Yan, et al, 2019; Zhao, Jian, et al, 2019).…”

“…The main factors affecting the membrane separation efficiency include membrane characteristics (i.e., membrane flux, membrane pore size, hydrophobicity) and pollutant characteristics (i.e., molecular weight, solubility, charge). At present, the research of membrane treatment is mainly focused on optimizing the process and developing the combined process of membrane treatment and other processes (Fan, Luo, et al, 2019; Fan, Li, et al, 2019; Li, Gao, et al, 2019; Li, Li, et al, 2019; Li, Zhang, Zeng, et al, 2019; Li, Liu, Zhang, Li, et al, 2019; Li, Zhang, Xia, Wang, et al, 2019; Li, Zhang, Hu, et al, 2019; Li, Sun, Zhang, Feng, et al, 2019; Li, Wang, et al, 2019; Li, Yuan, Gao, et al, 2019).…”

“…Li, Gao, et al (2019), Li, Li, et al (2019), Li, Zhang, Zeng, et al (2019), Li, Liu, Zhang, Li, et al (2019), Li, Zhang, Xia, Wang, et al (2019), Li, Zhang, Hu, et al (2019), Li, Sun, Zhang, Feng, et al (2019), Li, Wang, et al (2019), Li, Yuan, Gao, et al (2019)) studied the adsorption of three EPs (i.e., 1H‐benzotriazole (BTA), 5‐methyl‐1H‐benzotriazole (TTA), and 1‐hydroxybenzotriazole (HOBT)) and Cu 2+ in water by gemini surfactant‐modified montmorillonite (GSMM). The whole experiments were divided into two categories: the single adsorption of Cu 2+ by GSMM and the simultaneous adsorption of Cu 2+ and three EPs by GSMM.…”

“…As a treatment method for EPs, electrochemical oxidation (EO) has the advantages of high efficiency and good controllability (Li, Gao, et al, 2019; Li, Li, et al, 2019; Li, Zhang, Zeng, et al, 2019; Li, Liu, Zhang, Li, et al, 2019; Li, Zhang, Xia, Wang, et al, 2019; Li, Zhang, Hu, et al, 2019; Li, Sun, Zhang, Feng, et al, 2019; Li, Wang, et al, 2019; Li, Yuan, Gao, et al, 2019). However, there are some disadvantages, such as easy to produce degradation intermediates and electrode deactivation.…”
