Waller et al. (237) performed a CoMFA study to analyze the metabolic rates of CYP2E1 in rodents as intrinsic clearance of a 12 chlorinated volatile organic compounds (VOCs). After superimposition, the steric and electrostatic field interaction energies, the HINT (/jydropathic interactions) energy (238), and molecular orbital field were calculated in addition to clogP. The best model...

Dowex Optipore is a polymeric adsorbent used to treat chlorinated volatile organic compound (CVOC) contaminated off-gas streams from remediation processes such as air stripping of groundwater and soil vapor extraction. According to the vendor Dowex Optipore adsorbent has the following advantages over activated carbon ... 

The Dual Auger system is an in situ treatment for soils contaminated with volatile organic compounds (VOCs), chlorinated volatile organic compounds (CVOCs), and inorganics. This process uses specialized equipment to mix soil and inject reagents. The system can add nutrients to promote bioremediation, inject steam to volatilize contaminants, install zero-valent iron to promote chemical treatment, or add a pozzolanic slurry to stabilize the contaminants. The injection and mixing process effectively breaks down fluid and soil strata barriers. Mixing also eliminates pockets of contamination that would otherwise remain untreated.

Chlorinated volatile organic compounds (VOCs) are another important group of pollutants commonly studied. Literature reports include numerous works focusing on several types of advanced oxidations. These pollutants are present in water due to their use as cleaning agents, degreasers of metals, paint and ink constituents, etc. [137].

The increasing amounts of chlorinated volatile organic compounds (VOC), such as 1,2-dichloroethane (DCE) and trichloroethylene (TCE), released in the environment, together with their suspected toxicity and carcinogenic properties, have prompted researchers world-wide to find clean effective methods of destruction [1]. The abatement of chlorinated volatile organic compounds by catalytic combustion has been widely utilised in several technical processes. The lower temperatures required for catalytic combustion result in a lower fuel demand and can therefore be more cost effective than a thermal oxidation process [2]. In addition, the catalytic process also exerts more control over the reaction products and is less likely to produce toxic by-products, like dioxins, which may be generated by thermal combustion [3]. 

The effect of a wide range of feed concentration of PCE from 30 to 10,000 ppm on the stability of chromium oxide supported on Ti02 and AI2O3 for the removal of chlorinated volatile organic compounds (CVOCs) has been investigated over a fixed bed flow reactor. Both chromium oxide catalysts exhibited stable PCE removal activity up to 100 h of reaction time without any catalyst deactivation when 30 ppm was introduced into the reactor.

Rey et al. ° removed chlorinated aromatic hydrocarbon from a pharmaceutical plant by stripping the chlorinated hydrocarbons with air and then adsorbing in activated carbon beds. The removal of chlorinated volatile organic compounds such as trichloroethane, cis, and trans dichloroethane from ground water contaminated with these nonaqueous liquids was carried out by Yu et al." using activated carbon fibers. All the halogenated compounds were adsorbed rapidly by the activated carbon...
