Biodegradação de uma mistura de corantes têxteis usando o fungo Ganoderma sp: um estudo cinético Translated title: Biodegradation of dyes in textile wastewater by fungus Ganoderma sp: a kinetic study

Translated abstract

The kinetics of biodegradation by the fungus Ganoderma sp of textile dyes Yellow, Blue and Red Procion were studied in effluents using UV-Vis spectroscopy, Partial Least Squares Regression (PLS) and univariate analysis. The kinetic of the reactions were founded intermediate between first and second orders and the rate constants were calculated. The biodegradation after 72 h at 28 ºC were 33.6, 43.5 and 57.7% for the dyes Yellow, Blue and Red Procion, respectively. The quantitative analysis of the effluent by HPLC method can not be used without previous separation.
