A converse process is the smoothing of the original surface irregularities, which may occur when some foreign species, called an additive, is present in solution and adsorbs on the surface and inhibits the process of discharge.
Higher grades of plantation white are produced by a carbonatation purification process, in which carbon dioxide gas (scrubbed flue gas) is injected into juice and reacted with lime to form calcium carbonate, which absorbs and adsorbs nonsugars and is filtered off.
This is called an anodic reaction, and for the corrosion process to proceed there must be a corresponding cathodic reaction that adsorbs the electrons.
In warm climates, therefore, water loss by evaporation from lakes can be significantly reduced by introducing a solute that adsorbs positively at the lake-air interface.
Further, a copper-loaded chelating resin also adsorbs, by coordination, traces of amino acids from seawater.
Small quantities of dissolved water glass are used in the treatment of municipal water supplies as well as wastewater, where it adsorbs metallic ions and aids in the formation of loose agglomerations of particles called flocs, which filter the water of undesirable suspended materials.
