Abstract:

Polychlorinated Biphenyls (PCBs) have been widely used to flame-retard products common in homes and theworkplace, and subsequently. Polychlorinated biphenyls (PCBs) typify a class of highly toxic, stable aromaticpollutants. PCBs are recently being scrutinized for potential environment damage in groundwater and in theatmosphere. The elimination of chemical pollutants from a contaminated environment is one of the roostimportant steps towards achieving the goal of environmental remediation.Recent studies have used carbon mnombes (CNTs) for adsorption of pollution in environment, which aresignificantly higher dioxin elimination efficiencies In this study, mechanism and interaction of single-walledcarbon naotube (SWNT) for removal of PCBs are calculated by Gaussian program package. Inter SWNT; therearc four situations for PCBs near SWNT (6, 6) with length of 1.54 um that we calculated simulation of passingPCB through SWNT. The thermodynamics properties are calculated for passing PCBs across from SWNT thattheir results are showed this method can use for removal PCBs in environmental and their interaction are lowpotential in SWNT middle. So there is a place for adsorption of PCBs into SWNT, PCBs trap in it This passingis exothermic, spontaneous, and favorable.

Polychlorinated biphenyls (PCBs)(Arochlors)

Polychlorinated biphenyls (PCBs) are a group of chemicals that contain 209 individual compounds (known as congeners) with varying harmful effects. Information on specific congener toxicity is very limited. Most toxicity testing has been done on specific commercial mixtures; however, PCB mixtures found in the environment will differ in composition from the commercial mixtures because of partitio...

Some Chemical Aspects of Polychlorinated Biphenyls (PCBs)

In the past few years considerable scientific information has appeared on the chemistry and biological effects of the PCBs and related materials. The amount of chemical investigation, and especially the biological effects investigation that can be done on these products, is almost limitless. Even though the PCBs show a great deal of inertness, a property very useful in their industrial applicat...

Occupational exposure to polychlorinated biphenyls (PCBs).

Human occupational exposure to polychlorinated biphenyls (PCBs) with varying chlorine content has been reported by several investigators, using analyses of blood or adipose samples or skin wipes to evaluate levels in the body. The intensity of occupational exposure is related to both duration and intensity of exposure. The qualitative nature of occupational exposure, as well as casual environme...
