Photocatalytic Degradation of Bisphenol a in an Aqueous Suspension of Titanium Dioxide

Bisphenol A (BPA) is a monomer used in the epoxy resin and polycarbonate manufacture. This compound is catalogued like an endocrine disruptor that causes several diseases and syndromes. This is distributed as a result of its multiple use, to its low degradability, to that it can be transported by air, ground and water, to its bioaccumulation in the trophic chain because is accumulated in the fat of the organisms and, to that are transmitted to the descendants through the mother during the gestation. Human exposition to this non biodegrable substance is increasing in the time, particularly through contaminated water by industrial remainders. Considering that the water is one of main means where it is deposited as remainder of industrial processes is tried to create systems for water treatments and purification of the same. Nevertheless, the traditional technologies that are used for the separation of organic substances of the treated water are based on processes of adsorption with activated coal or by drag with air. This implies that these processes only transfer the polluting agents of their watery phase to other that is also contaminated, therefore the problem persists. This problem has generated the necessity to implement new processes to treat non biodegradable compounds [1-4].
