Manufacturing Quality Control of LIGNIN, ALKALI
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Total Lignin Content | UV-Vis Spectrophotometry | Measures absorbance at 280 nm, based on aromatic ring absorption of lignin chromophores. |
| Moisture Content | Karl Fischer Titration | Quantifies water via coulometric or volumetric titration with iodine-based reagent. |
| Ash Content | Gravimetric Analysis (Incineration) | Determines inorganic residue after high-temperature combustion at 575 C. |
| pH (1% aqueous solution) | Potentiometric pH Measurement | Uses calibrated pH electrode to measure hydrogen ion activity in standardized suspension. |
| Water Solubility | Filtration and Drying | Compares mass of dissolved fraction after filtration and drying under controlled conditions. |
| Acid-Insoluble Lignin | Gravimetric Analysis (Acid Hydrolysis) | Isolates residue after 72% H2SO4 hydrolysis and subsequent dilute acid digestion. |
| Heavy Metals (Pb, Cd, As, Hg) | ICP-MS | Quantifies trace metals by atomization, ionization, and mass-to-charge ratio detection. |
| Sodium Content | Flame Photometry | Measures sodium emission intensity at characteristic wavelength (589 nm) in atomized solution. |
| Viscosity (4% aqueous solution) | Capillary Viscometry | Determines kinematic viscosity by measuring flow time through calibrated capillary tube. |
| Particle Size Distribution | Laser Diffraction | Analyzes scattering pattern of dispersed sample to calculate size distribution. |
| Sulfur Content | Combustion IC (Ion Chromatography) | Oxidizes sulfur to sulfate, then quantifies SO4(2-) via suppressed conductivity detection. |
| Reducing Sugar Impurity | DNS (3,5-Dinitrosalicylic Acid) Assay | Measures reducing ends via colorimetric reduction of DNS reagent to red-brown complex. |
