Comparison of Four Adsorption Equations Used for the Description of the Systems: Porous Solid/Binary Liquid Non-Electrolyte Solution

The solution analogues of four single gas adsorption equations have been examined. The derived expressions have been applied to the description of the experimental adsorption isotherms on to microporous active carbons from binary liquid solutions with limited component miscibility. Statistical analyses of the individual adsorption equations, as well as comparisons of the optimized results obtained from different adsorption equations, have been undertaken

Adaptation of Single Gas Adsorption Equations for the Description of Adsorption from Non-aqueous Liquid Solutions of Iodine on to Active Carbons

The solution analogs of four single gas adsorption equations have been formulated. The derived expressions have been applied for the description of the experimental adsorption isotherms from binary liquid solutions with limited component miscibility on to microporous active carbons, as well as for the derivation of standard chemical affinity distribution functions

Adsorption of Cationic and Anionic Dyes onto Commercial Kaolin

Commercial kaolin from a Polish deposit has been examined as a low-cost adsorbent for effluent remediation using five cationic and five anionic industrial dyes. Methylene Blue dye was also used as a reference. The anionic dyes studied showed no affinity towards the kaolin surface, whereas the experimental isotherms for the adsorption of the cationic dyes could all be well described by the Langmuir equation. The values of the adsorption capacity of kaolin towards the cationic dyes ranged from 4 mg/g to 29 mg/g, being probably dependent on the geometry of the dye molecules. The resulting degrees of decolourization attained values of 85–90% for initial dye concentrations in the range 6–20 mg/dm 3 and for kaolin loadings of 0.5–3 g/dm 3 . Adsorption of the cationic dyes onto kaolin increased at higher solution pH values

Landscape Genomics: Understanding Relationships Between Environmental Heterogeneity and Genomic Characteristics of Populations

Landscape genomics is a rapidly advancing research field that combines population genomics, landscape ecology, and spatial analytical techniques to explicitly quantify the effects of environmental heterogeneity on neutral and adaptive genetic variation and underlying processes. Landscape genomics has tremendous potential for addressing fundamental and applied research questions in various research fields, including ecology, evolution, and conservation biology. However, the unique combination of different scientific disciplines and analytical approaches also constitute a challenge to most researchers wishing to apply landscape genomics. Here, we present an introductory overview of important concepts and methods used in current landscape genomics. For this, we first define the field and explain basic concepts and methods to capture different hypotheses of landscape influences on neutral genetic variation. Next, we highlight established and emerging genomic tools for quantifying adaptive genetic variation in landscape genomic studies. To illustrate the covered topics and to demonstrate the potential of landscape genomics, we provide empirical examples addressing a variety of research question, i.e., the investigation of evolutionary processes driving population differentiation, the landscape genomics of range expanding species, and landscape genomic patterns in organisms of special interest, including species inhabiting aquatic and terrestrial environments. We conclude by outlining remaining challenges and future research avenues in landscape genomics
