Industrial Applications of hypochlorous acid
| Industry | Applications | Process |
|---|---|---|
| Water Treatment | Disinfection of drinking water, swimming pool water, and wastewater | Direct dosing of hypochlorous acid solution or on-site electrolysis of low-concentration brine to generate hypochlorous acid; pH maintained at 5.0–6.5 to ensure the dominant active species is hypochlorous acid (HOCl) |
| Food Industry | Disinfection of food-contact surfaces and equipment, washing and disinfection of fruits and vegetables, disinfection of aquaculture water | Application via spraying, immersion, or rinsing at concentrations typically ranging from 20–200 ppm (as available chlorine), with contact time of 1–5 minutes; compliant with food safety standards such as GB 14930.2-2012 |
| Healthcare | Disinfection of environmental surfaces, hand disinfection (in selected alcohol-free formulations), and pre-cleaning of endoscopes | Use of stabilized hypochlorous acid water (pH 5.0–6.5, 20–200 ppm available chlorine); non-alcoholic and non-irritating, with contact time of 1–3 minutes; compliant with WS/T 650-2019 “Methods for Evaluating Antimicrobial and Bacteriostatic Efficacy” |
| Agriculture | Disinfection of livestock housing and farming equipment, seed disinfection, disinfection of greenhouse air and irrigation water | Application via spraying or fogging at concentrations of 50–100 ppm; avoid direct use in environments with high organic load; seed treatment typically involves immersion in 50–100 ppm solution for 10–30 minutes |
| Household & Personal Care | Household disinfectants, pet environment disinfectants, air deodorizing and antimicrobial sprays | Formulated as stable hypochlorous acid solution at pH 5.5–6.5, with small additions of buffering agents (e.g., phosphates) and chelating agents (e.g., EDTA) to enhance stability; typical concentration range: 50–150 ppm |
Manufacturing Quality Control of hypochlorous acid
| Detection Item | Common Detection Methods | Method Overview |
|---|---|---|
| Hypochlorous Acid Concentration | Iodometric Titration | Under acidic conditions, hypochlorous acid oxidizes potassium iodide to release iodine, which is then titrated with a standardized sodium thiosulfate solution. The concentration of hypochlorous acid is calculated based on the volume consumed. Suitable for relatively concentrated solutions; simple to operate with high accuracy. |
| Hypochlorous Acid Concentration | Spectrophotometry | Hypochlorous acid reacts with a specific chromogenic reagent (e.g., N,N-diethyl-p-phenylenediamine, DPD) to form a colored compound, whose absorbance is measured at a specific wavelength (e.g., 515 nm) and quantified via a calibration curve. Suitable for low-concentration detection with high sensitivity. |
| Free Chlorine (including hypochlorous acid) | DPD Colorimetry | DPD reagent rapidly reacts with free chlorine (including HClO and ClO⁻) to form a red compound; the intensity of color is measured using a colorimeter or spectrophotometer. Commonly used for rapid on-site detection, ideal for monitoring water disinfection. |
| Hypochlorous Acid Purity/Impurities | Ion Chromatography (IC) | Separates and detects anions in the sample (e.g., Cl⁻, ClO⁻, NO₃⁻) to assess impurity levels in hypochlorous acid solutions, used for quality control of high-purity products. |
| Analysis of pH Influence | pH Meter Combined with Concentration Measurement | The equilibrium between hypochlorous acid (HClO) and hypochlorite ion (ClO⁻) is strongly pH-dependent (pKa ≈ 7.5). By controlling pH and combining with other methods, the proportion of HClO to ClO⁻ can be determined to optimize disinfection efficacy assessment. |
| Stability Testing | Accelerated Degradation Test with Concentration Monitoring | Samples are stored under elevated temperature or light exposure, and hypochlorous acid residual concentration is periodically measured using iodometric titration or spectrophotometry to evaluate storage stability. |
