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 کاملStudies of Electrospun Cellulose Acetate Nanofibrous Membranes
The objective of this work was to study the feasibility of preparing cellulose acetate (CA) nanofibrous membranes by electrospinning with single solvent and their potential applying as affinity membrane. CA solutions in dichloromethane (DCM), formic acid, acetic acid and trifluoroacetic acid (TFA) were electrospun into nonwoven fiber membranes, respectively. The scanning electron microscope (SE...

distinguished from the color of fluorescein isothiocyanate. Figure 1 shows the mycelium and the cell walls stained by the method described. The staining reaction of these preparations could be observed as far as a 1:16 dilution of the antiserum. These results suggest that a-amylase may be located on the cell surfaces where the antibody molecules were accessible, although there is no information...
متن کاملSuspended, Porous Cellulose Acetate Membranes For Microdialysis Use
Porous cellulose acetate membranes were suspended over 75 micron wide silicon microchannels. The microchannels are formed when a viscous polymer lacquer is directly spin cast onto etched silicon cavities (Fig. 1). Standard fabrication processes are used to create the channel, preventing the need for adhesives, substrate bonding, or other complex assembly procedures. These microchannels can allo...
متن کاملSynthesis of Calcium Fluoride Ultrafine Particles for the Preparation of Integral Asymmetric Cellulose Acetate/Calcium Fluoride Membranes
The present work reports on the synthesis of cellulose acetate (CA) asymmetric membranes with the incorporation of inorganic fluorides, CaF2 particles. These fillers of polymeric composites can, according to the literature, promote the ordering of the polymer matrix, which can lead to interesting permeation properties. In order to achieve that, fluorite (CaF2 ) fine particles were prepared by a...
