MKP - Technical Requirements
1. Purity requirements: Potassium dihydrogen phosphate should be chemically pure, the purity should be above 99%.
2. Solubility: Potassium dihydrogen phosphate is easily soluble in water, so it is required to have good solubility.
3. Moisture content: Moisture content is an important technical indicator, generally not more than 1%.
4. Nitride (N) content: Nitride is a kind of impurity, which will have possible influence on the experiment or production process, and it is required that its content does not exceed 0.002%.
5. Heavy metal content: Heavy metals are toxic substances and a common impurity. The heavy metal content in potassium dihydrogen phosphate is required to be low, usually not more than 0.001%.
6. Crystallization performance: Potassium dihydrogen phosphate requires good crystallization performance to ensure the quality of its finished products.
7. Packaging requirements: Depending on the use requirements, potassium dihydrogen phosphate is usually packed in plastic bags or glass bottles sealed to avoid light, moisture and water.
