Nowadays, textile industries provide larger employers with few required special skills, which shows that it is one of the important industries with major economic role in many countries, which utilizes large amount of water and various chemicals. Like a coin with two sides, the waste water produced from those industries produce large amount of pollutants, which harmful for human and environment. By Photocatalytic method, organic and inorganic pollutants oxidised rapidly, show attractive field of technic for waste water treatment and water purification. An experimental setup consist of a closed box contains UV lamp surrounding aluminium foil is made. Under UV lamp, the synthetic sample is made and treated for four hours in the experimental setup containing TiO₂ and TiO₂-Cu doped catalyst. The background on these technologies as well as the theoryfor enhanced oxidation technology by photocatalysis. This paper specifically give attention on Photocatalytic semiconductor TiO₂and the recentlymodified TiO₂photocatalysts and its modification, including the addition of TiO₂ withmetal cupper metal powder, for variety of morphologies of TiO₂ physical modification, which enhance Photocatalytic activity for oxidation process in advance.
