Physicochemical property
| Molecular weight: 367.86 g/mol | Appearance: white crystalline or powdery solid. |
| Odor: Odorless or slightly sulphide odor. | Density: 2.52 g/cm³ (25°C). |
| Melting point: about 622°C (decomposition). | Chemical Safety: Unrestricted goods |
| Solubility:
Water: easily soluble in water, the aqueous solution is weakly alkaline (pH about 9-10);
Organic solvent: insoluble in ethanol, and other organic solvents. |
| Hydrolysis reaction:
It is gradually hydrolyzed in water to form orthophosphate |
| Complexation:
Form a soluble complex with metal ions (e.g. Ca² +, Mg² +) for softening hard water. |
| Thermal stability:
When heated to high temperatures (>600°C) it decomposes to form sodium phosphate and oxygen. |
| Acid base:
The aqueous solution is weakly basic and can react with acid to form phosphate. |
Efficacy of trisodium phosphate in water treatment
1. Water quality softens
Action: Reacts with calcium and magnesium ions in water to generate insoluble precipitation,
thus softening the water quality.
Reaction equation: 3Ca² + 2PO₄³⁻ → Ca₃(PO₄)₂↓
2. Prevent scale formation
Function: By chelating the calcium and magnesium ions in the water,
it prevents the formation of scale in the inner wall of the boiler and pipe.
Application: Widely used in boiler water treatment and cooling water system.
3. Corrosion inhibitors
Function: Form a protective film on the metal surface to prevent metal corrosion.
Application: Corrosion inhibition for boilers, heat exchangers and cooling water systems.
4. pH adjustment
Function: As an alkaline substance, it regulates the pH value of the water body and maintains the appropriate pH.
Application: Used for industrial wastewater treatment and swimming pool water treatment.
5. Dispersant
Function: Disperse suspended particles in water to prevent deposition and scaling.
Application: Used in circulating cooling water system and industrial water treatment.
6. Microbial control
Action: By increasing the pH value of water, inhibit the growth of microorganisms.
Application: For drinking water treatment and industrial water treatment.
7. Other applications
Flocculant: Used as a flocculant in some water treatment processes to help remove suspended solids.
Cleaning agent: Used to clean water treatment equipment and pipes to remove sediment and dirt.
