Abstract : Hazardous chemicals escape to the environment by a number of natural and/or anthropogenic activities and may cause adverse effects on human health and the environment. Pharmaceuticals are considered as emerging environmental contaminants. Because of their unique properties, behavior and fate, they cannot be simulated with other chemical organic contaminations. Many studies have reported a large variety of pharmaceutical compounds at concentrations ranging from nanogram per liter to milligram per liter in sewage treatment plant effluents, natural waters and even in drinking water. One of the most detected non-steroidal anti-inflammatory drug (NSAIDs) in seawaters at levels up to few hundred ng L−1 is Acetaminophen. The ecotoxicity of acetaminophen has become an important problem, it has been attributed to the production of a highly toxic metabolite formed by enzymatic oxidation in the liver. The technology of solar photochemical detoxification of polluted waters using nanostructured titanium dioxide (TiO2) has been proposed as an effective and economical method to convert organic pollutants in contaminated water to carbon dioxide, water and mineral acids, which are less toxic substances. In this research, visible light active carbon-modified (CM-n-TiO2) nanoparticles which are capable of absorbing the light in both UV and visible regions were successfully synthesized by sol-gel method. The research showed the potentiality of utilization and practical application of the synthesized CM-n-TiO2 nanoparticales as photocatalysts for the removal of acetaminophen from polluted seawater and aqueous solution under the illumination of both artificial UV light as well as real sunlight. The results of this research reveals that CM-n-TiO2 has the ability to be applied for a large scale with varies concentrations of AMP, in addition to other compounds in polluted water under the irradiation of both artificial UV light as well as real solar light.
