Abstract EN
A biomass agricultural waste material, olive stone (OS) was used for preparation of activated carbon (AC) by chemical activation using 50% phosphoric acid (PA5) carbonized at 800ºC and holding time 90 min (OSPA58).
The prepared AC was used for sorption of La (III) from nitrate solution.
The effect of various factors such as shaking time, pH, carbon dose, particle size and different temperature on the adsorption capacity of Lanthanum onto activated carbon were quantitatively determined.
The two equilibrium models; Langmuir and Freundlich, were discussed and the data were fit with Langmuir model with a monolayer capacity of 201.6 mg/g.
The kinetics of sorption was described by a pseudo second-order rate model.
Thermodynamic calculations pointed towards the feasibility of an adsorption process with spontaneous and endothermic nature with a value of ΔGº= -19.3 KJ/mol, ΔH=10.98KJ/mol and ΔS=12.89x10-2KJ/mol.
