Study Notes
Caking Diagram and Flocculation
- Caking diagrams illustrate how flocculating agents like monobasic potassium phosphate facilitate the flocculation of suspensions.
- Flocculation involves the aggregation of particles in a suspension, enhancing stability and preventing sedimentation.
Electrokinetic Phenomena
- This phenomenon describes the movement of a charged surface relative to an adjacent liquid phase.
- One significant application of electrokinetic phenomena is electrophoresis, a technique used to separate charged particles.
Electrophoresis
- Electrophoresis is defined as the movement of charged particles through a liquid under an applied electric potential difference.
- This technique is implemented in specialized electrophoresis cells, which include two electrodes to facilitate the dispersion of particles.
- It is commonly used in analytical chemistry for separating biomolecules such as DNA and proteins based on size and charge.
General Applications
- Understanding these principles is crucial for various applications in biochemical analysis, materials science, and environmental testing.
- Knowledge of electrokinetic phenomena can lead to innovations in drug delivery systems and nanotechnology.
