Как да изчислим Colloid

Какво е Colloid?

Colloid properties: suspensions of 1 nm-1 μm particles; colloidal stability depends on pH, ionic strength, surface charge.

Ръководство стъпка по стъпка

  1. 1Input particle size, charge, solution composition
  2. 2Calculate DLVO potential or colloidal stability
  3. 3Predict aggregation/sedimentation

Worked Examples

Вход
Oil-in-water emulsion: stability improved by surfactants reducing interfacial tension
Резултат
Surfactant concentration critical

Common Mistakes to Avoid

  • Neglecting DLVO interactions
  • Not accounting for pH effects on charge

Frequently Asked Questions

Why are colloids kinetically stable?

Brownian motion prevents settling; particles too small for gravity, too fast for diffusion aggregation.
