Özet

This study provides a comprehensive review of the effect of cetyltrimethylammonium bromide on the Reactive Black 5 adsorptive behavior of Candida tropicalis. Adsorption studies examining the effects of process parameters have shown the critical roles of initial pH and surfactant concentration on the dye sorption capacity of the yeast. The remaining RB5 dye in the adsorption medium was determined colorimetrically via spectrophotometer. RB5 removal capacity was found as 126.1 mg RB5/g dry biomass with 61.1% yield in the presence of untreated dry sorbent in medium including 200 mg/L of RB5 at pH 2. Moreover, the maximum RB5 sorption capacities of untreated and CTAB treated dry biomass increased from 186.9 to 350.5 mg RB5/g dry biomass when initial RB5 concentration adjusted to 800 mg/L in pH 2. CTAB treated biomass performed significantly higher in all cases studied, due to the synergistic effect observed. It was seen that the experimental sorption data were compatible with the saturation type kinetic model. RB5 uptake equilibrium was quickly reached for both sorbents, and the Langmuir model described the equilibrium of RB5 biosorption with high accuracy.
