Cellulose Acetate Nanofiltration Membranes for Cadmium Remediation
In this work, cellulose acetate (CA) nanofiltration (NF) membranes were prepared via non-solvent phase inversion technique (NIPS). Polymer concentration was varied from 22 to 25 wt% in order to study its effect on the membrane properties. The fabricated membranes were characterized in terms of morphological analysis using scanning electron microscopy (SEM), contact angle, water content, water p...
متن کاملThermal and Magnetic Characteristics of Cellulose Acetate- Fe3O4
Fe3O4 nanoparticles were synthesizedviaa simple chemical reaction between FeCl2.4H2O and Fe(NO3)3.9H2O under nitrogen atmosphere at room temperature, and then nanoparticles were added to cellulose acetate (CA) polymer. The influence of nanoparticles on the thermal properties of CA polymeric matrix was studied using the...
متن کاملThe Potentials and Applications of Cellulose Acetate in biosensor technology
The interest in cellulose and its derivatives has been exponentially increasing due to its excellent thermal stability, biocompatibility, chemical persistence and biodegradability. Among various cellulose derivatives, cellulose acetate (CA) has been applied in many applications including sensor systems, drug delivery systems, separation membrane, and tissue engineering. Recently, the electrospu...
متن کاملFunctionalization of cellulose acetate fibers with engineered cutinases.
In the present work, we describe for the first time the specific role of cutinase on surface modification of cellulose acetate fibers. Cutinase exhibits acetyl esterase activity on diacetate and triacetate of 0.010 U and 0.007 U, respectively. An increase on the hydroxyl groups at the fiber surface of 25% for diacetate and 317% for triacetate, after a 24 h treatment, is estimated by an indirect...
