摘要：
A novel adsorbent, poly(ethyleneimine)-modified poly(acrylic acid)-grafted nanocellulose/nanobentonite superabsorbent hydrogel (PEI-PAA-g-NC/NB) was prepared by free radical graft copolymerization technique and well characterized. Swelling behavior of adsorbent was studied under different pH and temperatures. The various adsorption parameters for the adsorption of the protein, beta-Casein (beta CN) onto the PEI-PAA-g-NC/NB were investigated. Sips adsorption isotherm and pseudo-first-order kinetic model were best suited for the present adsorbent. The adsorption-desorption experiments were conducted with 0.1 M NaSCN for four cycles. The results of the present investigation proved that PEI-PAA-g-NC/NB is highly effective for the separation of beta CN from aqueous solutions. [GRAPHICS] .
