| With these goals in mind, researchers at Eawag studied a series of methods in the laboratory, including complexation, precipitation, ozonation and various membrane processes such as nanofiltration and electrodialysis. |
| Element abundances vary in natural waters according to the solubility of their source minerals and the availability of surface-active particulates, which remove solutes from solution by adsorption or chemical complexation. |
| These smaller particles result in the exposure of larger surface areas to chemical attack, as well as biological processes that affect acidity and complexation reactions. |
| If any metal complexation route to produce ethylene is ever going to succeed commercially, olefin separation needs to compare favourably with cryogenics. |
| Surface complexation is an example of adsorption, a chemical process in which matter accumulates on a solid particle surface. |
| It is important to observe a waiting time of 3 min after each addition to allow complexation. |
