TY - JOUR ID - TI - Photocatalytic Degradation of Bleaching Some Organic Dyes with TiO2 under direct Sun Light AU - Hassan A.Habeeb , Batol S. Hussein , Azal S. Waheeb PY - 2013 VL - 1 IS - 1 SP - 260 EP - 277 JO - Muthanna Journal of Pure Science (MJPS) مجلة المثنى للعلوم الصرفة SN - 22263284 25725181 AB - The photocatalytic degradation of some dyes in aqueous solutions has beeninvestigated under solar radiation as energy source in the presence of TiO2. A dyesolution containing 1X10-5 M was completely degraded within 150 min. The effect ofinitial dye concentration, pH, light intensity and TiO2 mass were investigated and theoptimized conditions for maximum amount of degradation were determined.Experiments were performed at the range of temperature (33-40) ºC, The combinedeffect of pH and catalyst concentration was greater. The intensity of the solar light wasmeasured using digital lux meter. The higher removal efficiency was obtained for AzorC dye (88 %).
