Biosorption of cadmium (II) onto loquat leaves (Eriobotrya japonica) and their ash from aqueous solution, equilibrium, kinetics, and thermodynamic studies

Abstract: Simple methods for immobilizing titania into pumice were applied, where the products had been used for the application of photodegrading phenol waste. There were two simple methods, which were used separately: solvent evaporation and dip coating. Based on titania sol stability test, it was observed that acid condition would be favourable for immobilizing titania unto pumice, and preferable dispersion medium for solvent evaporation method was ethanol, while dip coating method was better to use aquadest (water).… Show more

“…The higher uptake at higher temperature may be attributed to the availability of more active sites on the surface of SPS, the same result was obtained by Al-Dujaili et al [25] on the Biosorption of cadmium (II) onto loquat leaves(Eriobotrya japonica) and their ash from aqueous solution, equilibrium, kinetics, and thermodynamic studies..…”

“…o is the free energy of adsorption (kJ/mol), T is the temperature in Kelvin and R is the universal gas constant (8. Table 4.Positive value of ΔS o and ΔH o showed increased randomness and that the adsorption process is endothermic [18].A negative value of the free energy (ΔG•) at all the temperature indicates the process to be feasible and spontaneous; the same result was gotten by [18] and also [25]. For physical adsorption free energy change (ΔG o ) ranges from (−20 to 0) kJ/ mol and for chemical adsorption it ranges between (−80 and −400) kJ mol−1 [18].…”

“…Recently, researchers are paying attention on the removal of Cd (II) from aqueous solution using adsorbents derived from low-cost tree leaves such as loquat leaves (Eriobotrya japonica) [10], Psidium guajava leaves [11], Maize leaves [12], Ulmus leaves [13], Scolymus hispanicus [14], Ulmus carpinifolia and Fraxinus excelsior tree leaves [15], fig leaves [16], Azadirachta indica (Neem leaves) [17], Olea europaea (Olive leaves) [18], and Prunus vium leaves [19].…”
