Mechanisms of Organic Contaminants Uptake and Degradation in Plants
As a result of urbanization, the unpredictable growth of industry and transport, production of chemicals, military activities, etc. the concentration of anthropogenic toxicants spread in nature exceeds all the permissible standards. Most dangerous among these contaminants are organic compounds having great persistence, bioaccumulation, and toxicity along with our awareness of their prominent oc...
متن کاملDISPERSION OF CONTAMINANTS IN GROUNDWATER WITH CHEMICAL REACTION
A mathematical model presented in this paper describes the dispersion and concentration ofcontaminants (fine and coarse) in porous medium with the effect of chemical reaction. Solutetransport in porous media is discussed by means of advection-dispersion equation. The effectof particle mass parameter and reaction rate parameter on the dispersion coefficient and meanconcentration of a chemical so...

Adsorption of Inorganic Contaminants in Ponded Effluents from Coal-fired Power Plants
The objectives of this study were [1] to conduct some experimental tests of the surface precipitation adsorption model, and [2] to work on the development of a simple yet widely applicable approach to modelling adsorption of inorganic ions on oxide surfaces. The latter represents the first portion of our continuing effort to develop a data base for adsorption of inorganic contaminants in oxide ...
متن کاملWastewater minimization in multipurpose batch plants with a regeneration unit: Multiple contaminants
Wastewater minimization can be achieved by employing water reuse opportunities. This paper presents a methodology to address the problem of wastewater minimization by extending the concept of water reuse to include a wastewater regenerator. The regenerator purifies wastewater to such a quality that it can be reused in other operations. This further increases water reuse opportunities in the pla...
