Abstract: Adsorption kinetics, isothermal adsorption and adsorption thermodynamics of naphthalene on PET fabric were investigated in this paper, the influence of temperature on adsorption of naphthalene also was determined. The adsorbed quantity of naphthalene on PET fabric is high, and the pseudo-second-order model fitted the sorption kinetics data well over the sorption duration; the linear sorption processes of naphthalene could be described by the linear model, and isothermal adsorption of naphthalene with the ascending of experiment temperature, the adsorbed quantity decreases; on the sorption duration of naphthalene on PET fabric, the adsorption thermodynamics ΔH0 is－16.494 kJ/mol and ΔG0＜0, these results indicate that adsorption of naphthalene is exothermic and spontaneous and the major forces are Bond dipole force and Hydrogen bond force．
