摘要
以主波长为254nm的紫外光灯为光源,TiO2为光催化剂,研究了对苯二酚光催化降解。建立了简单的符合拟一级的动力学模型,并进一步研究了其他因素如催化剂的活化温度、TiO2的用量以及酸度对降解率的影响。
Photocatalytic degradation of pyrocatechol was studied by using ultraviolet light of wavelength of 254nm as source and TiO_(2) as catalyst.A first order kinetic model was established,and other impact factors such as activating temperature,TiO_(2) dosage and acidity on degradability were also analysed.
