The synthesized PC/nano-Fe 3O 4 composite with a Fe 3O 4/PC mass ratio of 1/5 exhibited a maximum adsorption capacity of 2682.1 μg/g as well as a complete TCPP degradation within 3 h in a Fenton-like system. However, the PC/Fe 3O 4 containing low Fe 3O 4 content (10%) had insufficient magnetic separation ability from water. The PC/nano-Fe 3O 4 composite prepared by high Fe 3O 4 content (25%) was not favorable for TCPP adsorption and degradation. The effect of Fe 3O 4 content on TCPP adsorption and degradation performance by PC/nano-Fe 3O 4 composite was investigated.
In this study, a ball-milling method was used to prepare a magnetic powdered carbon adsorbent (PC/nano-Fe 3O 4 composite) for TCPP removal via adsorption and catalytic degradation. Electronic address: phosphate (TCPP) as a widely used typical chlorinated organophosphate flame retardant has received significant attention because of its widespread presence in water and negative effects on human health. 5 State Key Joint Laboratory of Environment Simulation and Pollution Control (SKLESPC), Beijing Key Laboratory for Emerging Organic Contaminants Control, School of Environment, Tsinghua University, Beijing 100084, China.Electronic address: 1 State Key Joint Laboratory of Environment Simulation and Pollution Control (SKLESPC), Beijing Key Laboratory for Emerging Organic Contaminants Control, School of Environment, Tsinghua University, Beijing 100084, China State Key Laboratory of Plateau Ecology and Agriculture, Qinghai University, Xi'ning, Qinghai Province 810016, China. 4 State Key Joint Laboratory of Environment Simulation and Pollution Control (SKLESPC), Beijing Key Laboratory for Emerging Organic Contaminants Control, School of Environment, Tsinghua University, Beijing 100084, China.
