Special Topic 6.28 Environmental remediation

Homogeneous transition metal photocatalysis reactions generating HO radicals, often referred to as advanced oxidation processes (AOP),1518 are powerful methods to remediate (i.e. to remove or to destroy) organic pollutants from aqueous solutions.1519

In pursuance of the above decrees by a special decision of RF Minatom, Ministry of Defense and Ministry of Economic Development (May 20, 1998) a work group had been established, which developed a time-schedule of topical works to be executed in support of the program of complex decommissioning of NS and environmental remediation of radiation-hazardous naval facilities in Kola Peninsula and the Arkhangelsk region. The time-schedule comprised the following activities ... 

The most important and widespread applications of photochemistry are, of course, photoimaging techniques, such as photography and xerography (Special Topic 6.32).1313 Some other large-scale applications, such as environmental remediation of anthropogenic pollutants by photocatalytic processes (Special Topic 6.28) and potential applications such as photoelectrochemical cells (Special Topic 6.31) and artificial photosynthesis (Special Topic 6.26), are also discussed in the following text. 

Interest in soil decontamination by electrokinetic processing has been increasing steadily, as shown by the volume of scientific studies. There have been two workshop/conferences dedicated to this topic in the U.S. in recent years [86,87] and a number of companies now have offered specialized services in this area. The technology is an emerging one and it is not yet fully mature. There exists a need to conduct further basic and applied studies before it achieves its full potential. In environmental remediation, the site chemistry before and after any application of technical processes need to be fully evaluated. It is recommended that bench scale, laboratory tests be undertaken prior to any site work to help optimize the process parameters. Although the...
