在紫外灯照射下，920（DB 2）染料在去离子水中于25 ℃下于（nm）处发生光分解。该染料的吸收光谱已被记录与照射的时间，以检查光衰减的动力学。计算了一级反应的比速率常数Kd = 0.0248min ~（-1）。研究各种参数如催化剂负载量、介质pH值和初始染料浓度的影响。920（DB2）的光分解
Photo decomposition of 920 (DB2) dye have been performed at (nm) in deionized water at 25C˚.Under irradiation Uv Lamp. The absorbance spectrum for this dye have been recorded with the time of irradiation in order to examine the kinetics of photo decay. The specific rate constant the (Kd) for the first order reaction have been calculated and found to be (Kd = 0.0248 min-1). Study the effect of various parameters such as catalyst loading, pH of the medium and initial dye concentration. On photodecomposition of 920 (DB2)
