Industrial Applications of Iron hydroxide oxide
| Industry | Application | Process |
|---|---|---|
| Water Treatment | Sewage purification; removal of phosphates and arsenic | Used as an adsorbent in precipitation and filtration processes to effectively remove anionic contaminants from water |
| Catalysis | Catalyst support for chemical synthesis | Used to immobilize other active components, facilitating catalytic reactions in gas-phase or liquid-phase processes |
| Pigments & Coatings | Production of red/brown pigments | Applied as an inorganic pigment in architectural coatings, paints, and colored cement products |
| Pharmaceuticals | Pharmaceutical excipient or intermediate for iron supplements | Used as an excipient in specific drug formulations or for manufacturing iron-containing pharmaceuticals |
| Electronic Materials | Precursor for magnetic materials | Serves as a raw material for preparing magnetic oxide materials such as ferrites |
| Environmental Remediation | Soil and groundwater remediation | Applied via in-situ injection to immobilize heavy metal contaminants, including chromium(VI) and lead |
Manufacturing Quality Control of Iron hydroxide oxide
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Chemical Composition (Fe₂O₃·nH₂O Content) | Titration Method (e.g., Potassium Dichromate Method) | The sample is dissolved in acid, and Fe³⁺ is reduced to Fe²⁺ using a reducing agent (e.g., SnCl₂). Then, it is titrated with a K₂Cr₂O₇ standard solution to calculate the total iron content. The water content from moisture determination is used to estimate the hydrated iron(III) oxide content. |
| Moisture/Crystallization Water Content | Thermogravimetric Analysis (TGA) or Drying Loss Method | TGA measures mass changes as a function of temperature under programmed heating conditions to determine dehydration temperature range and weight loss percentage; the drying loss method involves drying at 105–110°C until constant weight is achieved to calculate moisture content. |
| Crystal Phase Structure | X-ray Diffraction (XRD) | X-rays are directed at the sample. The diffraction peak positions and intensities are compared with standard PDF cards (e.g., goethite α-FeOOH, lepidocrocite γ-FeOOH) to identify phase composition and crystallinity. |
| Particle Size and Morphology | Scanning Electron Microscopy (SEM) or Transmission Electron Microscopy (TEM) | SEM observes particle surface morphology and size distribution; TEM provides further information at the nanoscale level, including lattice fringes and selected area electron diffraction patterns. |
| BET Surface Area | Nitrogen Adsorption-Desorption Method (BET) | A nitrogen adsorption isotherm is measured at liquid nitrogen temperature, and the BET equation is used to calculate the specific surface area, reflecting the dispersion and pore structure characteristics of the material. |
| pH Value | pH Meter Measurement Method | A certain amount of sample is dispersed in deionized water (typically prepared as a 10% suspension), allowed to stand for equilibrium, and then the pH value is measured using a calibrated pH meter to assess surface acidity or alkalinity. |
| Impurity Elements (e.g., As, Pb, Cd, etc.) | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) or Atomic Absorption Spectroscopy (AAS) | After strong acid digestion of the sample, ICP-MS or AAS is used to quantitatively analyze trace heavy metal impurities to ensure compliance with relevant safety or pharmacopoeia standards. |
| Color and Appearance | Visual Color Comparison or Colorimeter Measurement | Color conformity is visually assessed using standard color charts; alternatively, a colorimeter can be used to measure L*, a*, b* values to quantify color parameters for batch consistency control. |
