Sodium silicate flocculant properties are also used to clarify wine and beer by precipitating colloidal particles.

But colloidal particles are big enough to be blocked by parchment paper or animal membrane.

Now, for reasons that I won't go into now, all colloidal particles must carry an electric charge.

These forces tend to cause colloidal particles to aggregate or to flocculate.

PCE's backbone, which is negatively charged, permits the adsorption on the positively charged colloidal particles.

This approximation has been used to estimate the force between two charged colloidal particles as shown in the first figure of this article.

Heavy-metal cations, such as cadmium, nickel, lead, manganese and mercury, may be bound to colloidal particles in the soil.

I wouldn't have seen colloidal particles.

This approximation is widely used to estimate forces between colloidal particles, as forces between two planar bodies are often much easier to calculate.

The electrodipping force is a force proposed to explain the observed attraction that arises among small colloidal particles attached to an interface between immiscible liquids.
