Algae (Chlorella,Microcystis, Oocystis and Scenedesmus) degradation by ultraviolet radiation has been investigated. The radiation source was a low pressure mercury vapor lamp which emits monochromatic radiation at 254 nm. Experiments include initial algae concentration variation. After a period of exposure to UV radiation, algal mass concentration was reduced by more than 80%. The results were interpreted under Line Source Spherical Emission model, so quantum yield was the appropriate target variable for explaining the process. Global quantum yields are determined for Chlorella, Microcystis, Oocystis and Scenedesmus being 7.75 ×10 4, 3.65 ×10 5, 2.28 ×10 5, 1.74 ×10 4 μg E-1, respectively.
