Chlorinated organic chemicals such as 1, 2, 3-trichlorobenzene (TCB), monochlorobiphenyl (BPCl), and magnetic recording tape were subjected to grinding with and without an additive to decompose their structures mechanochemically. The additive was CaO, and the mill used in the experiment was a planetary mill. After the grinding, a washing operation using water was conducted to separate the soluble compound from the product by filtration. The ground product and the filtrate were characterized by ion chromatography (IC), gas chromatography (GC/MS), X-ray diffraction (XRD), Raman spectroscopy, electron spin resonance (ESR) and inductivity coupled plasma (ICP). The conversion of the chlorinated organic chemicals was almost 100% by prolonged grinding, where radicals played a significant role in the decomposition and the yield of the ground samples. This operation would be applicable to the decomposion of other chlorinated organic substances.
