  • 摘要: 为了探讨电絮凝法去除水中四环素的效能及机理，分别研究了电极材料、电流强度、电导率和四环素初始浓度等参数对电絮凝去除四环素的影响；并通过氧化性能评估实验、UV-vis光谱分析、X射线衍射(XRD)等方法探究电絮凝去除四环素的性能。结果表明：使用铁电极(面积300 mm × 80 mm，厚2 mm)，对初始浓度0.05 mmol·L-1的四环素模拟废水进行处理，在电流强度为0.3 A、电导率为1 000 μS·cm-1、电解15 min时，四环素和总有机碳(TOC)的去除率分别可达99.6%和79.8%，并且约41.9%的四环素通过氧化降解作用从水中被去除。使用铁电极电絮凝技术能够快速高效地去除四环素，具有高氧化率、低成本的特点。
    Abstract: In this study, the electrocoagulation (EC) technology was investigated for tetracycline (TTC) removal from aqueous solution. The effects of electrode materials, current intensity, conductivity and initial TTC concentration on TTC removal by EC were examined. The performance of TTC removal by EC was studied through oxidation performance evaluation experiment, UV-vis absorption spectra and XRD analysis. Results showed that for TTC simulated wastewater with initial TTC concentration of 0.05 mmol·L-1 , the removal rates of TTC and TOC by EC with iron electrode(area=300 mm × 80 mm, thickness=2 mm) could reach up to 99.6% and 79.8%, respectively, after 15 min electrolysis at the current of 0.3 A and conductivity of 1 000 μS·cm-1. About 41.9% TTC was removed by oxidative degradation. EC technology with iron electrode could efficiently remove TTC, which has an excellent oxidation performance and low cost.
