In this work, it is studied the electrolysis with diamond anodes of three different ionic liquids (ILs): 1-butyl-3-methylimidazolium chloride (BmimCl), 1-hexyl-3-methylimidazolium chloride (HmimCl) and 1-decyl-3-methylimidazolium chloride (DmimCl), which differ only in the length of the aliphatic carbon chain attached to the imidazolium group. In addition, the effect of the presence of sulfate in the electrolyte is also evaluated. Results confirmed that this type of ILs can be completely transformed into carbon dioxide, nitrates, ammonium (the imidazolium cation) and perchlorate and chloramines (the chloride anion) during the electrolysis of the synthetic waste containing sulfate. The electrolysis of wastes without sulfate anions leads to a much less efficient process, with the same final products in the case of the BminCl and HminCl ILs and with the formation of a polymer as the main final product in the case of the DmimCl. These results are of a paramount significance from a mechanistic point of view since, because of the high conductivity of the ILs, there is not a necessity of salt addition and they inform about the pure removal of these compounds by electrolysis with BDD, pointing out the important influence of peroxodisulfate on the electrolyses with diamond of organic wastes.

在这项工作中，研究了三种不同离子液体（IL）的金刚石阳极电解：1-丁基-3-甲基咪唑氯化物（BmimCl），1-己基-3-甲基咪唑氯化物（HmimCl）和1-癸基-3 -氯化甲基咪唑鎓（DmimCl），仅在连接到咪唑鎓基团的脂肪族碳链的长度上不同。另外，还评估了电解质中硫酸盐的存在的影响。结果证实，在电解含硫酸盐的合成废物的过程中，这种类型的IL可以完全转化为二氧化碳，硝酸盐，铵盐（咪唑鎓阳离子），高氯酸盐和氯胺盐（氯阴离子）。没有硫酸根阴离子的废物的电解会导致效率大大降低，对于BminCl和HminCl IL，其最终产物相同，而对于DmimCl，则以聚合物的形成为主要最终产物。从机械的观点来看，这些结果具有极其重要的意义，因为由于IL的高电导率，不需要添加盐，并且它们提示通过BDD电解将这些化合物纯净去除，指出了这一点。过氧二硫酸盐对金刚石与有机废物电解的重要影响。
