摘要
在紫外灯的照射下,以二氧化钛作催化剂,采用紫外 可见分光光度计来定性和定量描述玫瑰红降解过程中官能团的变化,用总有机碳(TOC)和化学需氧量(COD)2个参数来确定玫瑰红的降解程度,并借助紫外 可见图谱对玫瑰红的光催化机理作了有益的探索,并比较了光催化降解与直接光解(不加催化剂)的降解过程,可知反应过程表现出很大的差异。
Under the ultraviolet lamp, degradation process of rose red by TiO_2 is studied. In the experiment, three testing means UV-VIS,TOC and COD are used respectively. Through UV-VIS, functions can be determined and the quantity of them are fixed also. TOC and COD can indicate the extent decompose of Rose Red distinctly. Degradation pattern of Rose Red has been studied in this article. The two different processes with TiO_2 or without TiO_2 are compared.
