Adsorption behavior of PAHs(naphthalene) on PET fabric

The adsorption kinetics,isotherm and thermodynamics of naphthalene on PET fabric were investigated,and the influence of temperature on the adsorption of naphthalene also was discussed.Results indicated that the adsorption kinetics could be fitted by the pseudo-second-order model well,and the isothermal adsorption could be described by the Frenundlich model.It was discovered that PET fabric could adsorb a large amount of naphthalene,and with the rise of experiment temperature,the adsorbed quantity decreased in the studied range.By thermodynamics analysis,the adsorption enthalpy change ΔH0 and the adsorption free energy change ΔG0 were observed,which indicated that the adsorption process of naphthalene on the PET fabric is exothermic and spontaneous.
