ABSTRACT

The degradation of coragen (C₁₈H₁₄N₅O₂BrCl₂) 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⁻² 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.

摘要

通过使用石墨电极的电氧化过程测试了珊瑚碱（C ₁₈ H ₁₄ N ₅ O ₂ BrCl ₂ ）的降解。此外，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珊瑚礁中去除溴化物的优势。使用初始pH、电解时间和电流密度等三个不同的变量来分析电解过程对coragen降解的影响。在电解过程中，在各个阶段，对化学需氧量（COD）、氯化物和溴化物等参数进行了分析。最大COD、氯离子和溴离子去除效率分别为96%、50%和99%，在pH 5，最大电流密度7.5 mA cm^达到-2和120 分钟的电解时间。根据本研究的最终结果，可以得出结论，电解过程可以有效降低水介质中珊瑚的 COD、氯化物和溴化物。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证实了珊瑚的降解效率。
