Recently, the methods of the degradation of p-chloronitrobenzene (p-CNB) have been studied by numerous scholars. In the present study, Al-Ga-In-Sn alloy was found to be able to effectively remove p-CNB. When the initial concentration of p-CNB was 10 µM, and the Al-Ga-In-Sn alloy dosage was 0.25 g, the p-CNB completely mineralized within 30 mins. The effects of the initial temperature, alloy dosage, pollutant concentration, pH and inorganic anions on the removal of organics were studied systematically. To characterize the alloy, XRD, SEM, XPS, HRTEM, EDX and DSC were respectively used, and the results thereof were used for proposing the mechanism of the reduction reaction. The reduction of p-CNB can be divided into four processes. The present study provides consideration of the utilization of Al-Ga-In-Sn alloy in the abatement of refractory pollutants in environments, in addition to an understanding of the mechanism of said system.

近年来，许多学者对降解对氯硝基苯（p-CNB）的方法进行了研究。在本研究中，发现 Al-Ga-In-Sn 合金能够有效去除 p-CNB。当 p-CNB 初始浓度为 10  µM，Al-Ga-In-Sn 合金用量为 0.25  g 时，p-CNB 在 30 分钟。系统研究了初始温度、合金用量、污染物浓度、pH值和无机阴离子对有机物去除的影响。分别使用XRD、SEM、XPS、HRTEM、EDX和DSC对合金进行表征，其结果用于提出还原反应的机理。p-CNB的还原可分为四个过程。除了了解所述系统的机制外，本研究还考虑了利用 Al-Ga-In-Sn 合金减少环境中的难熔污染物。
