Enhanced Degradation of Chloramphenicol in Soil Using Activated Carbon Fiber Supported Nanoscale ZeroValent Iron Coupled with Microwave Irradiation
The objective of this research was to study the degradation of chloramphenicol (CAP) in soil using activated carbon fiber supported nanoscale zerovalent iron (ACF/NZVI) coupled with microwave (MW) irradiation.Compared to activated carbon fiber (ACF)/MW system, nanoscale zerovalent iron (NZVI)/MW system and MW alone, ACF/NZVI/MW system showed a high degradation efficiency.MW power was proven to be an important factor for MW processing, and more MW power generated higher removal of CAP.About 420 mg/kg CAP was removed at 10 min and almost 640 mg/kg CAP was removed at 30 min.The results showed that a larger microwave absorption dosage led to a higher removal amount of CAP in the soil.Using ACF/NZVI as a medium, the microwave treatment was an efficient method for degrading chloramphenicol.The time needed to achieve a satisfactory treatment was reduced leading to significant savings of energy consumption and making this method cost-effective.Hence, this technology is expected to be a cost-effective and environmental friendly microwave treatment.
