| Abstract The effect of pH on the photocatalytic oxidation of butan-2-ol over naked titanium dioxide has been investigated. The apparatus which is used in the photocatalytic reaction has a precies temperature control which gives a high precision for the reaction . Spectrophotometric method was used in the determination of amount of the product formed, this method is based on the formation of 2,4 – dinitrophenyl hydrazone of the produced carbonyl product, followed by the addition of alcoholic potassium hydroxide to give a wine colour which is measured by spectrophotometric method . The measurements were done at 298 K using different buffer solutions, and irradiation with ultraviolet light from mercury vapour lamp( 150 ) Watt . | ||
