Estudo Da Toxicidade De Efluente Têxtil Tratado Por Foto-Fenton Artificial Utilizando as Espécies Lactuca Sativa E Artemia Salina

Abstract: Resumo: Este trabalho apresenta a análise da toxicidade de efluente têxtil tratado por processo fotoFenton com irradiação artificial, utilizando alface (Lactuca sativa) e micro-crustáceos (Artemia salina) como organismos-teste. Foram retiradas alíquotas do efluente nos tempos de tratamento de 0, 5, 10, 15, 45, 60 e 90 minutos para análise da toxicidade, demanda química de oxigênio (DQO), cor e turbidez. Durante o experimento de toxicidade determinou-se a inibição do crescimento das raízes e radículas da alface… Show more

“…There was not germination in tests of raw effluent without dilution and for the dilution of 1:6, probably due to the presence of toxic components, such as formaldehyde. Palácio et al (2012) obtained 100% inhibition of the potential germination of Lactuca sativa seeds for the textile industry, with a decrease of the inhibition percentage for the same diluted effluent. Borba et al (2008), in a test with Lactuca sativa, identified a reduction of 50% in the toxicity of furniture industry effluent after the treatment of the effluent by the photo-fenton method.…”

“…The tests were performed to analyze the subacute toxicity, checking at the end of the procedure the length of the highest root of each onion, performing the measurement with ruler. The root growth of the Allium cepa in the control condition was used as a parameter, and from that parameter root growth inhibition ratios (ICR) exposed to treated effluent and untreated effluent were developed, using Equation 1, according to the methodology proposed by Palácio et al (2012):…”

“…Seus processos são responsáveis por consumir elevada quantidade de água, que posteriormente é convertida em efluentes ricos em compostos nocivos ao meio ambiente. (CHEN et al, 2011;PALÁCIO, 2012). O setor têxtil de Pernambuco é considerado um dos polos economicamente mais importante no estado.…”
