Abstract

Heterogeneous electro-Fenton is one of the promising technologies to degrade refractory organic phosphonates. In this work, CoNWs@CoAl-LDHs/FeO and CoNPs@CoAl-LDHs/FeO were successfully synthesized by a co-precipitation method and applied to degrade 1-hydroxyethane-1,1-diphosphonic acid (HEDP) and glyphosate (PMG) an electro-Fenton process. The results indicated that the removal rate of HEDP (100 mg L) and PMG (100 mg L) by CoNWs@CoAl-LDHs/FeO increased from 62.09% and 95.31% to 82.45% and 100%, respectively. The CoNPs@CoAl-LDHs/FeO electro-Fenton system could remove 70.03% of HEDP and nearly 100% of PMG within 2 hours at a pH of 3. Moreover, we compared the SEM, EDS, XRD and BET results of CoNWs@CoAl-LDHs/FeO with those of CoNPs@CoAl-LDHs/FeO. The effects of initial pH, CoNW dosage and reaction time on the degradation of HEDP and PMG were discussed. CoNWs@CoAl-LDHs@FeO could even remove 71.03% of HEDP at a neutral pH. After four cycles of repeated use at a pH of 3, the removal rate of HEDP by CoNWs@CoAl-LDHs/FeO was still higher than 70%. Radical quenching experiments revealed that ˙OH is the dominant active species participating in the heterogeneous electro-Fenton process. Finally, we would talk about the mechanism of the CoNWs@CoAl-LDHs/FeO-based electro-Fenton system.

摘要

非均相电芬顿是降解难降解有机膦酸盐的一种很有前景的技术。在本工作中，通过共沉淀法成功合成了CoNWs@CoAl-LDHs/FeO和CoNPs@CoAl-LDHs/FeO，并将其应用于电芬顿过程中降解1-羟基乙烷-1,1-二膦酸（HEDP）和草甘膦（PMG）。结果表明，CoNWs@CoAl-LDHs/FeO对HEDP（100 mg/L）和PMG（100 mg/L）的去除率分别从62.09%和95.31%提高到了82.45%和100%。CoNPs@CoAl-LDHs/FeO电芬顿体系在pH为3时，2小时内可去除70.03%的HEDP和近100%的PMG。此外，我们比较了CoNWs@CoAl-LDHs/FeO和CoNPs@CoAl-LDHs/FeO的扫描电子显微镜（SEM）、能谱（EDS）、X射线衍射（XRD）和比表面积（BET）结果。讨论了初始pH、CoNW用量和反应时间对HEDP和PMG降解的影响。CoNWs@CoAl-LDHs@FeO在中性pH下甚至可以去除71.03%的HEDP。在pH为3的条件下重复使用四个循环后，CoNWs@CoAl-LDHs/FeO对HEDP的去除率仍高于70%。自由基猝灭实验表明，˙OH是参与非均相电芬顿过程的主要活性物种。最后，我们将探讨基于CoNWs@CoAl-LDHs/FeO的电芬顿体系的作用机理。
