Bisphenol A(BPA) was determined by on-line preconcentration on self-assembly adsorption column filled with fibres from cigarette filter tips coupled with high-performance liquid chromatography(HPLC).The mobile phase was methanol-deionized water(90:10 in volume ratio).The thermodynamics properties and the possible mechanism of adsorption process for Bisphenol A on carbon nanotubes(CNTs) in aqueous solution were studied and the isotherm adsorptions at different temperstures were determined.The results show that the adsorption of BPA on CNTs is a quick adsorption.The adsorption amount of BPA on CNTs in aqueous solution at 20 ℃ reached to 24.65 mg/g when the concentration was 70 mg/L. At ambient temperature,the adsorption amount was increased with increasing of initial concentration or dropping of temperature.The correlation coefficients were larger than 0.99 when both Langmuir equation and Freundlich equation were used to fit data.Thermodynamic parameters such as ΔG,ΔH and ΔS are-39.48~-43.51 kJ/mol,-18.06 kJ/mol and 71.73 J/(mol·K),respectively.The adsorption proved to be a spontaneous process having a characteristic of physical adsorption.In addition,lower temperature is beneficial to accelerating the adsorption.
