Glass and cellulose acetate fibers-supported boehmite nanosheets for bacteria adsorption

Freundlich Adsorption Isotherm and Electrochemical Characterization of Cellulose acetate-Tween-20 supported liquid membrane

Cellulose acetate (CA) and Tween-20(T-20) are interacted and resulted as a supported liquid membrane system. The membrane potential was measured with uni-uni valent electrolyte, NaCl solutions using saturated calomel electrodes (SCEs).The effective fixed charge density of the membrane was determined by TMS method. Other important electrochemical parameters were calculated. Membrane adsorb-abili...

All-Cellulose Composite Fibers Obtained by Electrospinning Dispersions of Cellulose Acetate and Cellulose Nanocrystals

All-cellulose composite fibers were produced by electrospinning dispersions containing cellulose acetate (CA) and cellulose nanocrystals (CNCs). Precursor polymer matrices were obtained after dispersion of CA with different degrees of substitution in a binary mixture of organic solvents. The obtained fibers of CA loaded with CNCs had typical widths in the nanoand micro-scale and presented a gla...

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...

Hierachical Porous Carbon Structures from Cellulose Acetate Fibers

This study describes the transformation of cellulose acetate filters into porous carbon structures by a facile, direct process. Filters from cigarettes were used as the source for cellulose acetate filters. Carbon was obtained by high-temperature treatment under inert conditions without extensive preparative methods. The resulting carbon materials showed structural features on different length ...
