Abstract |
Cellulose acetate (CA) membranes are synthesized for filtration purpose. The hydrophilic
sericin macromolecule is blended with CA to analyze the enhancement of protein rejection. Increase
in hydrophilicity, water permeation and protein rejection was studied by using contact angle, pure
water flux (PWF) and Bovine serum albumin (BSA) permeation respectively. Surface modification
was examined using SEM and AFM. The results show the homogenous blending of sericin in CA
matrix and effective fabrication of membranes. In order to gauge the efficiency of casted membranes
in protein filtration and separation, water flux and protein rejection were studied. The concentration
of sericine protein was altered in CA polymeric solution that imparts variable properties to fabricated
membrane samples. Increment in wt. % of sericine up to 7.5 in polymer dope solution, enhances BSA
rejection to the limit of 96%. The amino linkages between sericine and the BSA of feed resulted in
the holding of protein by
