Role of pH in partitioning and cation exchange of aromatic amines on water-saturated soils
Predicting the reversible interactions between aromatic amines and soil is essential for assessing the mobility, bioavailability and exposure from contaminated sites. Reversible sorption mechanisms of aniline and α-naphthylamine ...
Novel tunable optical filter employing a fiber loop mirror for synthesis applications in WDM
A novel optical filter employing a fiber loop mirror within an amplified ring resonator is presented. The fiber loop mirror allows tuning by changing the coupling factor of a coupler. The device can be used as a building ...
Modeling Competitive Cation Exchange of Aromatic Amines in Water-Saturated Soils
Competitive association to several components of soil through ion exchange processes influences the fate of organic cations in the environment. To examine these processes, the distributions of aniline and 1-aminonaphthalene ...
Remoção de íons de metais pesados com bentonitas modificadas
O presente trabalho apresenta o desenvolvimento de um material sorvente a partir de bentonitas brasileiras modificadas quimicamente com o objetivo de aumentar sua capacidade de sorção de metais pesados e seu valor agregado. ...
