THERMOMECHANICS OF OIL-PROOF AGENT ADSORPTION ON CELLULOSE FIBERS
Calculated thermodynamic functions for exploring the nature of the adsorption solution to help us control the use of adsorption has an important significance. We use Freudlich equation to get the Oil-Proof Agent (OPA) adsorption isotherm at three typical temperatures 283K, 298K, 308K . This paper made the further deduction of isothermal adsorption enthalpy of the fitting equation Y=-0.59271+1410.51223X and calculated the thermodynamic parameters of adsorption to obtain isosteric enthalpy 11727J/mol at three typical temperatures of 283K, 298K and 308K. we also deduce the adsorption entropy仮S were丗58.03364 J/(mol.K)丆 55.48758 J/(mol.K) and 56.58478 J/(mol.K). Gibbs free energy 仮G were 丗-4696.52 J/mol丆-4808.3 J/mol 丆 -5701.11 J/mol丆仮G <0, indicate that the spontaneous adsorption. Increase of Adsorption entropy (仮S>0)is because the OPA adsorption process is a process of increasing the degree of fragmentation.
