DEGRADATION OF DYE RED REMAZOL RB BY UV/H2O2

DEGRADATION OF DYE RED REMAZOL RB BY UV/H2O2

Many industrial activities, including the textile industry, use a large volume of water in the process and produce a huge amount of wastewater. Chemical oxidation, including the Advanced Oxidation Processes (AOP), is one of the alternative technologies for the treatment of dye containing effluents. AOP is based on the generation of highly oxidizing hydroxyl radicals (.OH) which can decompose quickly and non-selectively the compounds, leading to their partial or complete mineralization. The paper aimed to study UV/H2O2 AOP for the degradation of the dye Remazol Red RB 133%, and the evaluation of experimental conditions such as hydrogen peroxide concentration, pH and potency of UV lamp on the process kinetics. It was observed that at 240 minutes irradiation time, all color was removed by using a dosage of 1% H2O2 and the COD removal was 78.4%. The pH 3, 6 and 8 did not influence the color removal, however at pH 10 a difference was found. COD removals at pH 3, 6 and 8 were higher which suggest a dye mineralization increase with the pH. However, COD removal at pH 10 did not show the same trend. The potency of UV lamp plays a role in the process in which 210 W was the best potency for color and COD removal. Therefore, AOP UV/H2O2 seems to be an interesting option for the treatment of textile effluents.Key Words: textile industry, AOP, mineralization, dye Remazol Red RB 133%, COD.

Muitas atividades industriais, incluindo a indústria têxtil, utiliza um grande volume de água no processo e produzuma grande quantidade de águas residuais. Oxidação química, incluindo os processos de oxidação avançada (POA),é uma das tecnologias alternativas para o tratamento de efluentes contendo corantes. POA baseia-se na geraçãode radicais hidroxilas (.OH) altamente oxidantes que pode decompor os compostos rapidamente e nãoseletivamente, levando a sua mineralização parcial ou completa . O artigo objetiva estudar o POA H2O2/UV para adegradação do corante Remazol Vermelho RB 133%, e a avaliação das condições experimentais, tais como aconcentração de peróxido de hidrogénio, pH e potência da lâmpada de UV sobre a cinética do processo. Observouseque em 240 minutos de tempo de irradiação, toda a cor foi removida usando uma dosagem de 1% de H2O2 e aremoção de DQO foi de 78.4 %. Os pH 3, 6 e 8 não influenciaram a remoção de cor, no entanto em pH 10 foiencontrada diferença. Remoções de DQO em pH 3, 6 e 8 foram maiores, que sugerem um aumento damineralização do corante com o pH. No entanto, a remoção de DQO em pH 10 não mostrou a mesma tendência. Apotência da lâmpada de UV desempenha um papel importante no processo, em que 210 W foi a melhor potênciapara a remoção de cor e DQO. Portanto, o POA UV/H2O2 parece ser uma opção interessante para tratamento deefluentes têxteis.Palavras Chave: indústria têxtil, POA, mineralização, corante Remazol Vermelho RB 133%, DQO.
