Biosorption is an effective treatment method for the removal of phenol and cyanide from aqueous solution by saw dust activated carbon (SDAC).
Batch experiments were achieved as a function of several experimental parameters, i.e.
influence of biosorbent dose (5–60 g/L) contact time (2–40 h), pH (4–12), initial phenol concentration (100–1000 mg/L) and initial cyanide concentration (10–100 mg/L) and temperature (20–40 C).
The biosorption capacities of the biosorbent were detected as 178.85 mg/g for phenol with 300 mg/L of initial concentration and 0.82 mg/g for cyanide with 30 mg/L of initial concentration.
The optimum pH is found to be 8 for phenol and 9 for cyanide biosorption.
The mono component biosorption equilibrium data for both phenol and cyanide were well defined by Redlich–Peterson model and binary component adsorption equilibrium data well fitted by extended Freundlich model.
The percentage removal of phenol and cyanide using SDAC was 66.67% and 73.33%, respectively.
Equilibrium established within 30 h for phenol and 28 h for cyanide.
Kinetic studies revealed that biosorption of phenol followed pseudo second order indicating adsorption through chemisorption and cyanide followed pseudo first order kinetic model indicating adsorption through physisorption.
Thermodynamic studies parameters, i.e., enthalpy (Dh0), entropy (DS0) and Gibb’s free energy (DG0) have also been considered for the system.
Thermodynamic modeling studies revealed that the process of cyanide biosorption was endothermic and phenol biosorption was exothermic in nature.
