Özet
The present study was conducted for the synthesis of a novel supermacroporous monolithic hydrophobic adsorbent for lysozyme (Lyz) selected as a model protein from aqueous solution. After preparation of poly(2-hydroxyethyl methacrylate-co-N-methacryloyl-(l)-tyrosine methyl ester) monolithic cryogel column, 1-naphthylamine was covalently attached, and the prepared column was abbreviated as NA-Mcc. Scanning electron microscopy, Fourier transform infrared spectroscopy and Brunauer, Emmett and Teller device were utilized for the morphology, functional groups and surface area measurements of the column. Effects of several parameters including Lyz content of the adsorption solution, pH of the medium used, ambient temperature, type of salt and flow rate on the adsorption capacity of the polymeric material were examined in continuous operation. The maximum value achieved for Lyz adsorption from aqueous phase was found to be 105.8 mg/g in phosphate buffer. In addition, NA-Mcc was investigated in terms of reusability, and it was demonstrated that there is no significant change in the adsorption properties of prepared monolithic hydrophobic cryogels after 30 adsorption-desorption cycles.
