Manufacturing Quality Control of MANGANESE (III) OXIDE
| Detection Item | Common Testing Methods | Method Overview |
|---|---|---|
| Main Component Content (Mn₂O₃) | Chemical Titration Method (e.g., Periodate Oxidation Method) | In acidic conditions, Mn³⁺ is oxidized to MnO₄⁻, and manganese content is determined by spectrophotometry or titration with a standard solution, then converted to Mn₂O₃ purity. |
| EDTA Complexometric Titration Method | Under appropriate pH conditions, Mn²⁺ ions are titrated with standard EDTA solution. This method is suitable for total manganese determination, and Mn₂O₃ content is calculated based on valence analysis. | |
| Moisture Content | Drying Loss Method | Sample is dried at 105–110°C until constant weight; moisture content is calculated from the mass loss. |
| Chloride Ion Content | Silver Nitrate Titration Method (Mohr's Method) | In neutral or slightly alkaline solution, chloride ions are titrated with standard AgNO₃ solution, forming a white precipitate. Chromate potassium is used as an indicator. |
| Ion Chromatography | Chloride ions are separated using an ion-exchange column and quantified by conductivity detection. High sensitivity makes it suitable for trace chloride detection. | |
| Loss on Ignition | High-Temperature Calcination Method | Sample is calcined at high temperature (e.g., 800–1000°C) for a specified time; the mass reduction is measured, reflecting the total amount of volatiles and decomposition products. |
| pH Value | pH Meter Measurement | Sample is dissolved in water in a given ratio, stirred, allowed to settle, and pH of the suspension is directly measured using a calibrated pH meter. |
| Particle Size Distribution | Laser Particle Size Analysis | Utilizes laser scattering principles to determine particle size distribution, suitable for physical property control of powdered Mn₂O₃. |
| Sieve Analysis | Sample is mechanically sieved through a standard sieve series to determine the mass percentage in different particle size ranges. Suitable for coarse particle analysis. | |
| Heavy Metal Impurities | Atomic Absorption Spectroscopy (AAS) | After sample digestion, AAS is used to determine the content of heavy metals such as lead, cadmium, mercury, and chromium. |
| Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | A high-sensitivity multi-element detection technique capable of simultaneously measuring multiple trace metal impurities, ideal for quality control of high-purity Mn₂O₃. | |
| Impurity Elements (Fe, Ca, Na, etc.) | Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) | After acid dissolution, the sample is excited in a high-temperature plasma, and the concentrations of impurity elements are quantified based on characteristic spectral line intensities. |
