Isotherm, kinetic analysis of the electrospun nylon affinity membranes
Electrospun nylon-6 nanofibrous membrane with fiber diameters in the range of 50-200 nm were prepared and employed as affinity membrane material for papain adsorption. In this work, Covalent coupling of chitosan (CS) to activated nylon membrane was performed after the reaction of the nanofibrous nylon membrane with formaldehyde. Cibacron Blue F3GA (CB F3GA) as a ligand was immobilized onto electrospun nylon membranes to produce high efficiency affinity membranes. Under batch equilibrium experimental conditions at 277, 298, and 310K was investigated. Two kinetic models were used to fit the experimental data at different initial concentrations, temperatures at pH 8.0. Studies showed that the adsorption of papain on dye nylon affinity membranes could be described by the Langmuir isotherm.
