Plant microbial fuel cells (PMFCs) has important value for soil remediation and power generation. To improve the performance of PMFCs, a PMFC experimental system was established based on potted scindapsus aureus. Polyaniline (PANI) and sodium alginate (SA) were used as modifiers to prepare PANI-SA modified carbon felt anode. The soil remediation ability and electricity generation ability of PMFCs with four different anodes were compared and analyzed. The experimental results show that the steady-state voltage, the removal rate of hexavalent chromium, and the total chromium removal rate of PMFC using PANI-SA modified anode were 5.25 mV, 98%, and 90%, respectively, which are 253%, 10.4%, and 10% higher than those of PMFCs using unmodified carbon felt anode. PMFC is effective and feasible for removing soil chromium pollution and achieving efficient soil remediation, while modifying anodes with PANI-SA can further improve the soil remediation and electricity generation capabilities of PMFC.
植物微生物燃料电池（PMFC）在土壤修复和发电方面具有重要价值。为了提高 PMFC 的性能，基于绿萝建立了 PMFC 实验系统。使用聚苯胺（PANI）和海藻酸钠（SA）作为改性剂，制备了 PANI-SA 改性碳毡阳极。比较和分析了具有四种不同阳极的 PMFC 的土壤修复能力和发电能力。实验结果表明，使用 PANI-SA 改性阳极的 PMFC 的稳态电压、六价铬去除率和总铬去除率分别为 5.25 mV、98%和 90%，分别比使用未改性碳毡阳极的 PMFC 高 253%、10.4%和 10%。PMFC 有效且可行，可用于去除土壤铬污染并实现高效土壤修复，而用 PANI-SA 改性阳极可以进一步提高 PMFC 的土壤修复和发电能力。
