With growing public concern about water quality particular focus should be placed on organic micropollutants, which are harmful to the environment and people. Hence, the objective of this research is to enhance the security and resilience of water resources by developing an efficient system for reclaiming industrial/military wastewater and protecting recipients from the toxic and cancerogenic explosive compound-2,4,6-trinitrotoluene (TNT), which has been widely distributed in the environment. This research used an anodic oxidation (AO) process on a boron-doped diamond (BDD) electrode for the TNT removal from artificial and real-life matrices: marine water and treated wastewater. During experiments, TNT concentrations were significantly decreased, reaching the anodic degradation efficiency of above 92% within two hours and > 99.9% after six hours of environmental sample treatment. The presented results show the great potential of AO performed on BDD anodes for full-scale application in the industry and military sectors for TNT removal.
随着公众对水质的关注度不断提高，应特别关注有机微污染物，它们对环境和人类有害。因此，本研究的目的是通过开发一种高效的工业/军事废水回收系统，并保护受纳水体免受已在环境中广泛分布的有毒致癌性爆炸化合物2,4,6-三硝基甲苯（TNT）的影响，来提高水资源的安全性和恢复力。本研究采用硼掺杂金刚石（BDD）电极上的阳极氧化（AO）工艺从人工和实际基质（海水和处理后的废水）中去除TNT。在实验过程中，TNT浓度显著降低，在环境样品处理两小时内阳极降解效率达到92%以上，六小时后>99.9%。所呈现的结果表明，在BDD阳极上进行的AO在工业和军事领域大规模应用于去除TNT方面具有巨大潜力。
