The degradation of coragen (CHNOBrCl) was tested by the electrooxidation process using graphite electrodes. Further, the advantage of nano-hydroxyapatite (n-Hap), as a cost-effective nano sorbent, in the removal of bromide from coragen was examined. Three different variables such as initial pH, electrolysis time and the current density were used to analyse the effects of the electrolytic process on the degradation of coragen. During electrolysis, under various stages, the parameters such as chemical oxygen demand (COD), chloride and bromide were analysed. The maximum COD, chloride and bromide removal efficiency of 96%, 50% and 99%, respectively, at pH 5, the maximum current density of 7.5 mA cm and 120 min electrolysis time were achieved. Based on the final output of this study, it can be concluded that the electrolysis process can effectively reduce COD, chloride and bromide from coragen in an aqueous medium. Further, the degradation efficiency of the coragen was confirmed through different analyses such as UV spectra, Fourier transform infrared spectroscopy and gas chromotography-mass spectrometry analyses.
采用石墨电极的电氧化法对考来烯胺（CHNOBrCl）进行了降解测试。此外，还研究了纳米羟基磷灰石（n-Hap）作为一种具有成本效益的纳米吸附剂，在从考来烯胺中去除溴化物方面的优势。使用初始 pH 值、电解时间和电流密度这三个不同变量来分析电解过程对考来烯胺降解的影响。在电解过程中，在不同阶段分析了化学需氧量（COD）、氯离子和溴离子等参数。在 pH 值为 5、最大电流密度为 7.5 mA/cm 和 120 分钟电解时间的条件下，COD、氯离子和溴离子的去除效率分别达到了 96%、50%和 99%。基于这项研究的最终结果，可以得出结论，电解过程可以有效地在水介质中降低考来烯胺中的 COD、氯离子和溴离子。此外，通过紫外光谱、傅里叶变换红外光谱和气相色谱-质谱分析等不同分析方法证实了考来烯胺的降解效率。
