Industrial Applications of Acid chrome blue K
| Industry | Application | Process |
|---|---|---|
| Analytical Chemistry | Metal ion titration indicator, primarily for endpoint detection of divalent metal ions (e.g., Ca²⁺, Mg²⁺, Zn²⁺, Cu²⁺) in EDTA complexometric titrations | In a buffered medium at pH 8.5–10.5 (e.g., ammonia–ammonium chloride buffer), forms a red complex with the target metal ions; upon completion of EDTA titration, the indicator is released, causing the solution color to change from red to blue |
| Water Quality Testing | Determination of total calcium and magnesium (water hardness) in drinking water, industrial recirculating water, and boiler water | Conforms to GB/T 7477-1987 “Water Quality—Determination of Total Calcium and Magnesium—EDTA Titrimetric Method”, using a mixed indicator of Acid Chrome Blue K and Naphthol Green B to enhance endpoint sharpness |
| Electroplating and Surface Treatment | Monitoring metal ion concentration and analyzing bath composition in electroplating solutions | Used in routine maintenance of nickel and zinc plating processes to rapidly determine Ni²⁺ and Zn²⁺ concentrations via complexometric titration, guiding replenishment of primary salts and complexing agents |
Manufacturing Quality Control of Acid chrome blue K
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Acidic Chrome Blue K content) | UV-Vis Spectrophotometry | Measures absorbance at characteristic wavelength (e.g., ~530 nm) and calculates concentration using Beer-Lambert law and reference standard calibration. |
| Moisture Content | Karl Fischer Titration | Quantifies water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Atomizes sample and measures absorption of specific wavelengths by ground-state metal atoms in flame or graphite furnace. |
| Sulfate (SO4) Impurity | Gravimetric Analysis | Precipitates sulfate as barium sulfate under controlled conditions and determines mass after drying and weighing. |
| Chloride (Cl) Impurity | Potentiometric Titration with AgNO3 | Uses silver nitrate titrant and silver indicator electrode to detect endpoint based on change in potential during AgCl precipitation. |
| pH of 1% Aqueous Solution | pH Potentiometry | Measures hydrogen ion activity using calibrated glass electrode and pH meter in standardized aqueous solution. |
| Solubility in Water | Visual Inspection and Filtration | Evaluates complete dissolution and absence of insoluble residue after specified stirring and standing time in distilled water. |
| Loss on Drying (LOD) | Thermogravimetric Analysis (TGA) | Determines mass loss upon heating to specified temperature (e.g., 105 C) under controlled atmosphere to quantify volatile components. |
| Iron (Fe) Impurity | ICP-OES | Atomizes and excites sample in plasma; quantifies Fe by measuring intensity of characteristic emission lines. |
| Arsenic (As) Impurity | Hydride Generation AAS (HG-AAS) | Converts arsenic to volatile arsine gas, which is swept into quartz cell for atomic absorption measurement. |
| Residue on Ignition | Weight Loss on Ignition | Heats sample at high temperature (e.g., 500-600 C) to oxidize organics; weighs residual inorganic ash. |
| Color Value (APHA) | Visual Comparison or Spectrophotometric APHA | Compares sample color against platinum-cobalt standard solutions or calculates APHA index from UV-Vis absorbance at 430 nm. |
