| Paper Industry | Used for paper dyeing and modification | Sulfonation and dyeing |
Manufacturing Quality Control of Trisodium naphthalene-1,3,6-trisulphonate
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Place an appropriate amount of sample on a white background and observe under natural light or standard illumination for color, physical state, and presence of impurities. 1,3,6-Naphthalenetrisulfonic acid sodium typically appears as a white to off-white crystalline powder. |
| Identification | Infrared Spectroscopy (IR) Ultraviolet-Visible Spectrophotometry (UV-Vis) |
Compare the characteristic absorption peaks of the sample with those of a reference standard using IR; or perform qualitative identification based on its UV absorption properties at specific wavelengths (e.g., 280–320 nm). |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with water-methanol or water-acetonitrile as the mobile phase, and detect with a UV detector (e.g., 254 nm or 280 nm). Quantify the main component using external standard method or area normalization method. |
| Drying Loss | Gravimetric Drying Method | Weigh the sample into a previously tared and constant-weight weighing bottle, dry at 105°C until constant weight is achieved, then calculate the percentage loss on drying to assess moisture and volatile substance content. |
| Residue on Ignition (Sulfated Ash) | High-Temperature Incineration Method | Char the sample first, then ignite it at 700–800°C in a muffle furnace until constant weight is reached. Weigh the residual ash to determine total inorganic impurities. |
| pH Value | pH Meter Measurement | Prepare a solution of specified concentration (e.g., 1% w/v), then measure pH using a calibrated pH meter to evaluate acidity or alkalinity compliance. |
| Heavy Metals | Thioacetamide Colorimetry (or Atomic Absorption Spectroscopy, AAS) |
Treat the sample according to pharmacopoeial procedures; in weakly acidic conditions, react with thioacetamide to form a colored precipitate, which is compared against a standard lead solution. Alternatively, use AAS to directly determine levels of heavy metals such as lead and cadmium. |
| Chlorides | Silver Nitrate Turbidimetry | Acidify the sample solution with nitric acid, then add silver nitrate. Compare the turbidity formed with that of a standard sodium chloride solution to control chloride impurity limits. |
| Sulfates | Barium Chloride Turbidimetry | Add barium chloride in a hydrochloric acid medium to generate barium sulfate turbidity, which is compared with a standard potassium sulfate solution to assess sulfate ion impurity levels. |
| Organic Impurities / Related Substances | High-Performance Liquid Chromatography (HPLC) | Utilize gradient or isocratic elution conditions to separate and detect potential synthetic by-products or degradation products. Control total impurities and individual impurity levels using area normalization or self-reference methods. |
