Industrial Applications of DEAE-cellulose
| Industry | Application | Process |
|---|---|---|
| Biopharmaceuticals | Protein purification (e.g., monoclonal antibodies, plasma protein separation) | Ion exchange chromatography; used as a weakly basic anion exchange medium for chromatographic column packing |
| Biochemical Research | Nucleic acid purification and separation | Anion exchange chromatography; selectively binds DNA/RNA and elutes via pH and salt concentration gradients |
| Food Industry | Food additive (stabilizer, emulsifier) | Added to dairy products and beverages to improve texture and stability (subject to regulatory limits such as GB 2760) |
| Cosmetics | Conditioning agent in hair and skin care products | Formulated into shampoos and conditioners as a cationic polymer, adsorbing onto negatively charged hair surfaces |
| Environmental Analysis | Enrichment and detection of heavy metal ions in water | Solid-phase extraction (SPE) sorbent; chelates metal ions such as Cu²⁺, Pb²⁺, and Cd²⁺ via amino groups |
Manufacturing Quality Control of DEAE-cellulose
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Assessment of physical form and color under controlled lighting conditions |
| Solubility in Water | Gravimetric Solubility Test | Sample is dispersed in water and undissolved residue is filtered and weighed |
| pH of 1% Aqueous Solution | Potentiometric pH Measurement | Hydrogen ion activity measured using calibrated pH electrode in standardized suspension |
| Substitution Degree (DE) | Acid-Base Titration | Free amino groups quantified by back-titration after acetic anhydride derivatization |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Drying | Weight loss measured after drying at 105 C for 2 hours under standard atmospheric pressure |
| Residue on Ignition | Ignition and Gravimetry | Inorganic ash content determined after combustion at 600 C in a muffle furnace |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-OES | Multi-element quantification based on atomic emission intensities following acid digestion |
| Chloride Content | Potentiometric Titration with AgNO3 | Chloride ions titrated with silver nitrate using silver indicator electrode |
| Sulfate Content | Barium Sulfate Gravimetry | Precipitation as BaSO4 followed by filtration, drying, and weighing |
| Viscosity (4% Aqueous Solution) | Rotational Viscometry | Shear stress response measured at defined temperature and shear rate using spindle viscometer |
| Microbial Contamination | Membrane Filtration and Plate Count | Viable aerobic microorganisms enumerated on soybean-casein digest agar after filtration |
| Assay (Purity by Nitrogen Content) | Kjeldahl Nitrogen Determination | Organic nitrogen converted to ammonium sulfate, distilled, and titrated with standard acid |
