Nucleophiles promotes the decomposition of electrophilic functional groups of tetracycline in ZVI/H2O2 system: Efficiency and mechanism

引用

Chinese Chemical Letters 2024年第10期35卷 440-446页

作者： Xin Li Wanting Fu Ruiqing Guan Yue yuan Qinmei Zhong Gang Yao Sheng-Tao Yang Liandong Jing song bai Key Laboratory of Pollution Control Chemistry and Environmental Functional Materials for Qinghai-Tibet Plateau of the National Ethnic Affairs Commission School of Chemistry and Environment Southwest Minzu University Key Laboratory of General Chemistry of the National Ethnic Affairs Commission School of Chemistry and Environment Southwest Minzu University Institute of Environmental Engineering RWTH Aachen University

When zero-valent iron（ZVI） is prepared and applied under neutral conditions, it is easy to form oxides or hydroxides on its surface, which hinders the electron release of ZVI. To this end, a nucleophile was introduced into the ZVI system to inhibit the precipitation of iron ions, improve the conductivity of the solution, and promote the removal efficiency of electrophilic functional groups in organic compounds. In this study, the addition of nucleophiles such as ethylenediamine, methylamine and dimethylamine to the ZVI/H2O2system resulted in an enhanced removal efficiency of tetracycline（TC） under neutral condition,while electrophiles such as EDTA-2Na and oxalic acid dihydrate impeded the removal of TC. Experimental results demonstrated that the presence of nucleophiles could effectively promote the release of iron ions and increase the proportion of ferrous in both aqueous solution and solid surface of ZVI. Experimental and theoretical calculation results revealed that the electrophilic functional group was eliminated in the TC molecule, and the toxicity of the treated solution was reduced significantly. Overall, this work provides a selection of the conditions and pollutants applicable to ZVI under neutral pH conditions.
