Response surface methodology (RSM) was employed to investigate the effects of different operational parameters on the biological decolorization of a dye solution containing malachite green (MG) in the presence of macroalgae Chara sp. The investigated variables were the initial pH, initial dye concentration, algae amount, and reaction time. Central composite design (CCD) was used for the optimization...
Biological decolorization of the triphenylmethane dye, Malachite Green (MG), by three microalgae, Chlorella, Cosmarium and Euglena species was investigated. Results indicated that the decolorization was dependent on reaction time, initial dye concentration, algal concentration, pH and temperature. The reusability and efficiency of the algae in long term repetitive operations were also examined. Since...
