A novel Cu/HAP@sBC composite as a persulfate activator for the removal of 2,4,6-trichlorophenol

摘要

As a typical chlorophenol, 2,4,6-trichlorophenol (2,4,6-TCP) is highly toxic and difficult to degrade. Here, we prepared a novel material (Cu/HAP@sBC) by combining copper-based hydroxyapatite with biochar, which removes 2,4,6-TCP via activated persulfate (PS). Cu/HAP@sBC was tested using various characterization methods. In addition, the removal of 2,4,6-TCP was up to 100% after 60 min, and the Cu/HAP@sBC/PS system had a broad pH application range (3  10). Based on the results, SO4  center dot, center dot OH, center dot O2  , and 1O2 were the main reactive species. Finally, the possible degradation pathways of 2,4,6-TCP were explored based on the intermediates identified by high-performance liquid chromatography-mass spectrometry (LC-MS).
