Definition of Peptization:
- Peptization is the Process of converting a precipitate into colloidal dispersion by adding a peptizing agent (usually an electrolyte or surfactant).
Mechanism of Peptization:
- Peptizing agent imparts electrical charge to the precipitate particles.
- This causes repulsion, breaking them into colloidal size.
Example:
- Fe(OH)₃ precipitate + FeCl₃ → Fe(OH)₃ colloid.
Use in Pharma:
- Preparation of metal sols for injectable or diagnostic formulations
