Water Purification: Any of several processes in which undesirable impurities in water are removed or neutralized; for example, chlorination, filtration, primary treatment, ion exchange, and distillation. It includes treatment of waste water to provide potable and hygiene water in a controlled or closed environment as well as provision of public drinking water supplies. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)

Diffusion and Osmosis- Concept

Cell Membranes and Diffusion

In order to function, cells are required to move materials in and out of their cytoplasm via their cell membranes. These membranes are semipermeable, meaning that certain molecules are allowed to pass through, but not others. This movement of molecules is mediated by the phospholipid bilayer and its embedded proteins, some of which act as transport channels…

Source: Laboratory of Dr. B. Jill Venton - University of Virginia


Ion-exchange chromatography is a type of chromatography that separates analytes based on charge. A column is used that is filled with a charged stationary phase on a solid support, called an ion-exchange resin. Strong cation-exchange chromatography preferentially separates…
