The measure of copper and iron content in three cellulose acetate membrane of the zinc-silver battery by using the AIR- C2H2 flame atomic- absorption spectroscopy and make synthetically consideration of the measuring conditions and factors were atuded.

The rapid growth of various LCD products provides the great opportunities to expand the applications of TAC film.

Determination of Iron in Cellulose Acetate Membrane by Atomic Absorption Spectrometry;

This research has been focused on the affect of ultrasound on the reversed osmosis and permeability of some dyes with different molecular weights(sizes)such as bromothymol blue and a kind of dyewaste water,through cellulose acetate membrane.

Separation of Egg Albumin by Acetylcellulose Film Electrophoresis;

The electrophoresis of egg white using acetylcellulose film was conducted and the electrophoretogram showed that there were at least 6 major proteins, in which 5 of isoelectric point <pH8.

The structure and properties of cellulose triacetate acetylation were determined by IR,1H-NMR,XRD,DSC and chemical analysis.

The factors,including triphenyl phosphate(TPP) content,hydrolization time,the volume of water and catalyzer concentration,affecting degree of substitution(DS) of cellulose triacetate(CTA) in hydrolization are studied.

With cellulose triacetate (CTA) as membrane material, thiophen sulfone as solvent, and polyethyleneglycol(PEG) with proper amount of other additives as multi-element pore-forming agent, a high performance hollow fiber nanofiltration (NF) membrane is prepared by gel-freezing method.

The cellulose triacetate (CTA) prepared by heterogeneous acetylation and coated on small pore 3 aminopropyl silica gel (10nm) was used as chiral stationary phase for HPLC (OA column).
