Trends and strategies of ozone application in environmental problems

Abstract: Recebido em 20/4/05; aceito em 24/6/05; publicado na web em 20/1/06Efforts presented by the scientific community in recent years towards the development of numerous green chemical processes and wastewater treatment technologies are presented and discussed. In the light of these approaches, environmentally friendly technologies, as well as the key role played by the well-known advanced oxidation processes, are discussed, giving special attention to the ones comprising ozone applications. Fundamentals and applie… Show more

“…The redox potential of ozone is 2.1 V [28]. It can oxidize water because the redox potential of water is equal to 1.8 V [28], making a number of reactive compounds and including hydrogen peroxide formation [29]. The hydrogen peroxide in the aerated buffer solution was analyzed under the same conditions as described above.…”

“…18,22 Dentre os diversos POA's existentes, a ozonização é um importante processo coadjuvante para o tratamento de diferentes efluentes contendo uma alta carga de compostos recalcitrantes. [25][26][27][28][29][30] De modo geral, a eficiência de um POA depende das características químicas do efluente a ser tratado, tais como, pH, turbidez, COT-DQO e da presença de radicais aceptores. 20 No caso específico da ozonização, a eficiência depende do COT do efluente.…”
