Adsorption of safranin-O dye by peanut shell-based polyurethane type foam

The adsorption of safranin-O dye was performed in batch and continuous column sysytems by polyurethane-type rigid foam produced from peanut shell. In batch system, effects of contact time, initial dye concentration, solution pH and temperature on the adsorption were investigated. In column system, solution flow rate and initial dye concentration effect were studied. Under conditions studied, the adsorption of safranin-O was 95-99% for batch system, and 93-99% for column system. Adsorption isotherm best followed the Langmuir model (R2 = 0.986). Adsorption kinetics was in consistent with best the pseudo-second order model (R2values ≥ 0.998). Adsorption was of sponteneous nature and in favor of increasing temperature (i.e. endothermic nature). For example, when the temperature was increased from 20 to 60°C, standard Gibbs free energy change (ΔG°) dereased regularitly from -5303 to -8170 J mol-1. The values of standard enthalpy (ΔH°) and standard entropy (ΔS°) were estimated as 13.35 kJ mol-1 and 0.64 kJ mol-1 K-1, respectively. Moreover, FTIR and SEM analyses were done, and the results were interpreated in detail.
