Resolution for the Kinetic Process of Ultrasound-Assisted Electro-Catalytic Degradation of Benzoic Acid
【摘要】 基于苯甲酸超声辅助电降解过程的动力学 光谱两维数据矩阵 ,利用固定窗口尺寸渐进因子分析法确认了该降解过程中中间体的存在 ,继而根据迭代目标转化因子分析法、最小二乘回归等化学计量学方法求得了各吸光组分的表观动力学谱 ,结合组分间存在等吸收点这一光谱特征 ,求得了各吸光组分特别是难于直接测量的中间体的实际动力学谱及吸收光谱。进一步研究了苯甲酸的超声辅助电催化氧化降解过程的动力学模型。
【Abstract】 The two-way kinetic-spectral data can be acquired by monitoring the process of the ultrasound-assisted electro-catalytic degradation of benzoic acid. The product of absorbing intermediate is confirmed by FSMWEFA(Fix-sized Moving Window Evolving Factor Analysis). The real kinetic spectra and absorption spectra, which are hard to measure directly, are resolved by ITTFA (Iterative Target Transformation Factor Analysis) combined with the isoabsorptive points between components. The kinetic model of benzoic acid degradation is also studied.
