Abstract EN
Textile industries generate large quantities of dye containing wastewater which pose a serious environmental problem.
Currently, biosorbents have become desirable for the removal of dyes from textile effluents.
In this study, batch experiments were conducted to investigate the biosorption characteristics of cactus peel on the removal of reactive red dye from aqueous solutions.
The effects of solution pH, biosorbent dosage, contact time, and initial concentration were studied.
The interaction effects of process variables were analysed using response surface methodology.
The results showed that removal efficiency increased as initial dye concentration and solution pH decreased and as biosorbent dosage and contact time increased.
The highest removal efficiency (99.43%) was achieved at solution pH, initial dye concentration, biosorbent dose, and contact time of 3.0, 40 mg/l, 6 g, and 120 min, respectively.
From regression analysis, the Langmuir isotherm was found to better (R2 = 0.9935) represent the biosorption process as compared with the Freundlich isotherm (R2 = 0.9722).
Similarly, the pseudo-second-order model was seen to represent very well the biosorption kinetics.
The results show that cactus peel has good potential for the removal of reactive red dye.
