The mineralisation kinetics of petroleum refinery effluent (PRE) by Fenton oxidation were evaluated. Within the ambit of the experimental data generated, first-order kinetic model (FKM), generalised lumped kinetic model (GLKM), and generalized kinetic model (GKM) were tested. The obtained apparent kinetic rate constants for the initial oxidation step (k'2), their final oxidation step (k'1), and the direct conversion to endproducts step (k3') were 10.12, 3.78, and 0.24 min(-1) for GKM; 0.98, 0.98, and nil min(-1) for GLKM; and nil, nil, and >0.005 min(-1) for FKM. The findings showed that GKM is superior in estimating the mineralization kinetics.
评估了芬顿氧化法处理炼油厂废水（PRE）的矿化动力学。在生成的实验数据范围内，对一级动力学模型（FKM）、广义集总动力学模型（GLKM）和广义动力学模型（GKM）进行了测试。GKM在初始氧化步骤（k'2）、最终氧化步骤（k'1）和直接转化为终产物步骤（k3'）中获得的表观动力学速率常数分别为10.12、3.78和0.24 min(-1)；GLKM分别为0.98、0.98和零min(-1)；FKM分别为零、零和>0.005 min(-1)。研究结果表明，GKM在估算矿化动力学方面更具优势。
