Removal of aniline blue dye using live microalgae Chlorella vulgaris
Keywords:Biosorption, Aniline Blue, microalgae Chlorella v.
In this work, the efficiency of the microalgae Chlorella vulgaris was evaluated in the removal of aniline blue dye, one of the most demanded dyes in the tanning industry; evaluating the effect of the initial concentration of 25, 50, 75 and 100 mg/L of dye on the percentage of removal of aniline blue. The removal of the dye was evaluated by measuring the absorbance in a UV-VIS spectrophotometer of the bleached solutions until 11 days of treatment were completed. All treatments presented dye removal. By means of ANOVA analysis it was demonstrated that the removal of the dye depends on the initial concentration and the removal time; the best results in the 11 days of treatment were obtained at an initial concentration of 75 mg/L of aniline blue.
