quality index
1. Main content: Generally, the mass fraction of sodium sulfite is required to be ≥ 96.0%, and some high-end products can reach 97% or even higher. The high content ensures its effective role in various applications.
2. Iron content: It is usually stipulated that the mass fraction of iron (Fe) is ≤ 0.003%. A low iron content can avoid contaminating the product or affecting its color during use.
3. Water insoluble content: The mass fraction of water insoluble content is generally ≤ 0.03%, which reflects the purity and impurity content of the product. Low water insoluble content ensures the solubility and effectiveness of the product in water.
4. Free alkali content: Calculated as sodium carbonate, the mass fraction of free alkali is generally ≤ 0.40%. An appropriate free alkali content helps maintain the chemical stability and safety of the product during use.
