Dialysis.<\/p>\n<p>Colloids are a mixture of two or more substances where one substance is dispersed in another substance in the form of very small particles. The dispersed substance is called the dispersed phase, and the substance in which it is dispersed is called the dispersion medium. The particles of the dispersed phase are too small to be seen with the naked eye, but they are large enough to scatter light. This is why colloids are often called &#8220;colloidal suspensions.&#8221;<\/p>\n<p>Colloids can be purified by a variety of methods, including dialysis.
