| 1 | Recycling of waste aluminum scraps to fabricate sulfidated zero-valent iron-aluminum particles for enhanced chromate removal显示文摘Massive waste aluminum scraps produced from the spent aluminum products have high electron capacity and can be recycled as an attractive alternative to materials based on zerovalent iron(Fe^(0))for the removal of oxidative contaminants from wastewater.This study thus proposed an approach to fabricate micron-sized sulfidated zero-valent iron-aluminum particles(S-Al^(0)@Fe^(0))with high reactivity,electron selectivity and capacity using recycled waste aluminum scraps.S-Al^(0)@Fe^(0)with a three-layer structure contained zero-valent aluminum(Al^(0))core,Fe^(0) middle layer and iron sulfide(FeS)shell.The rates of chromate(Cr(Ⅵ))removal by S-Al^(0)@Fe^(0)at pH 5.0-9.0 were 1.6-5.9 times greater than that by sulfidated zero-valent iron(S-Fe^(0)).The Cr(Ⅵ)removal capacity of S-Al^(0)@Fe^(0)was 8.2-,11.3-and 46.9-fold greater than those of S-Fe0,zero-valent iron-aluminum(Al^(0)-Fe^(0))and Fe^(0),respectively.The chemical cost of S-Al^(0)@Fe^(0) for the equivalent Cr(Ⅵ)removal was 78.5%lower than that of S-Fe^(0).Negligible release of soluble aluminum during the Cr(Ⅵ)removal was observed.The significant enhancement in the reactivity and capacity of S-Al^(0)@Fe^(0)was partially ascribed to the higher reactivity and electron density of the Al0core than Fe^(0).More importantly,S-Al^(0)@Fe^(0) served as an electric cell to harness the persistent and selective electron transfer from the Al^(0)-Fe^(0) core to Cr(Ⅵ)at the surface via coupling Fe^(0)-Fe^(2+)-Fe^(3+)redox cycles,resulting in a higher electron utilization efficiency.Therefore,S-Al^(0)@Fe^(0) fabricated using recycled waste aluminum scraps can be a cost-effective and environmentally-friendly alternative to S-Fe^(0) for the enhanced removal of oxidative contaminants in industrial wastewater. | Yahui Zhang Liguo Zhang Jiajia Zeng Shuqun Xu Jianyu Pan Wenzhuo Huang Jianliang Sun Feng Jiang | 2024 | Journal of Environmental Sciences2024，，4： | 0 |
| 2 | 台州典型电子废物拆解区土壤中铜的迁移规律模拟显示文摘为研究典型电子废物拆解区土壤中铜(Cu)的迁移规律,以浙江台州某典型电子废物拆解区为例,通过等温吸附实验、土柱实验和HYDRUS-1D软件探究堆积渣体在降雨淋溶情景下溶出的Cu在包气带土壤中的迁移风险。结果表明:Cu在包气带土壤中的等温吸附符合Langmuir方程,Langmuir吸附常数(K_(L))和最大吸附量(q_(m))分别为0.065 L/kg和6024 mg/kg。两点模型(TSM)能很好地模拟Cu在土柱中的穿透过程(R^(2)=0.995),在TSM的应用中需重点关注入渗量、平衡吸附参数、土壤容重的代表性与准确性。利用TSM得出,研究区土壤中Cu浓度的模拟值与实测值具有一致性。进一步的迁移模拟表明,当堆积渣体所溶出的Cu质量浓度为20 mg/L时,历经100年降雨淋溶,包气带底端淋出液中Cu质量浓度为0.54 mg/L,未超过《地下水质量标准》(GB/T 14848—2017)Ⅲ类水质标准(1 mg/L),表明该降雨淋溶情景下地下水不存在Cu的污染风险,Cu污染主要存在于包气带土壤中。 | 刘金河 周长瑞 郑宇娜 刘鹏 王琪 黄凯 林匡飞 | 2022 | 环境污染与防治2022，44，11： | 0 |
