中文摘要：
采用幂指数方程法建立了转盘液膜光电催化法降解罗丹明B（RhB）废水的动力学方程。结果表明，该反应动力学符合表观一级动力学。在考察的影响因素中，外加偏压对反应速率的影响最大，催化剂用量次之，其次是RhB初始浓度，转盘转速和光强度的影响相对较小。
英文摘要：
Exponential function was employed to establish the kinetics model of Rhodamine B （RhB） photoelec trocatalytic degradation using rotating disk liquid film reactor. Result demonstrates the target reaction kinetics is con sistent with the apparent firstorder kinetics. Among the investigated influencing factors ,applied bias potential is the most remarkable factor that affecting RhB photoelectrocatalytic rate; the following ones are photocatalyst quantity and initial RhB concentration. Effect of rotating speed and light intensity on RhB photoelectrocatalytie degradation is rela tive low.
