Applications of 10138-04-2
| Industry | Application | Process |
|---|---|---|
| Water Treatment | Flocculant | Hydrolyzes in water to generate ferric hydroxide colloids, which aggregate suspended particles and colloidal impurities via charge neutralization and adsorption-bridging; applied in raw water purification and wastewater treatment. |
| Analytical Chemistry | Indicator | Serves as an adsorption indicator in the Volhard method for titrating halides (e.g., chloride determination in table salt) using standardized silver nitrate solution; yields a red precipitate at the endpoint. |
| Analytical Chemistry | Preparation of Iron Standard Solutions | Used as a primary or certified reference material; dissolved and diluted for instrument calibration, standard curve generation, or quantitative analysis. |
| Pharmaceutical Industry | Hemostatic Agent | Leverages the astringent effect of ferric ions; formulated into solutions or preparations for topical hemostasis and wound contraction. |
| Dyeing and Printing Industry | Mordant | Forms complexes with dyes during dyeing to enhance dye affinity and colorfastness on textiles; commonly used in mordant dyeing processes. |
| Microbiology and Research | Bacterial Testing | Added to hydrogen sulfide test media (e.g., as ammonium iron(III) sulfate); certain bacteria metabolize sulfur-containing amino acids to produce hydrogen sulfide, which reacts with ferric ions to form black ferrous sulfide precipitate for bacterial identification. |
| Electroplating Industry | Electroplating Additive | Serves as a main salt or additive component in zinc or iron electroplating baths to supply ferric ions, improving deposit crystallinity and bath performance. |
| Leather Tanning Industry | Tanning Agent | Exploits the cross-linking effect of ferric ions to bind with collagen fibers in hides, enhancing fiber stability during leather tanning. |
| Photographic Materials Industry | Etchant | Applied in etching or bleaching steps during the manufacture of certain photographic materials. |
