Abstract The article highlights sorptive properties of poultry litter. Preliminary studies on sorption Cd 2+ , Cu Ni Pb Zn ions at the concentration range 1–1000 mg L -1 were carried out. Langmuir and Freundlich models used to determine potential capacities Sorption parameter outcome from isotherms exhibited following order: > Ni. During batch adsorption experiment, a decrease absorbance sol...

This paper reports on the difficulties encountered when developing an analytical method for ultra-trace determination, in a complex matrix, of plastic additive residues which are ubiquitous laboratory. The simultaneous qualitative and quantitative determination antioxidant (2,6-di-tert-butyl-4-methyl-phenol, BHT), UV stabilizer (benzophenone, BP), plasticizer (diisobutyl phthalate, DiBP), relea...

Abstract Moisture absorption in the cell wall structure of wood is well known to induce considerable swelling exerting high expansion forces. This mainly induced by sorptive action hydroxyl groups carbohydrate polymers; cellulose and hemicelluloses. On ultrastructural level, there are, however, still questions with regard detailed deformations this moisture absorption. Here, FTIR spectroscopy s...

Olfactory sensory neuron (OSN) responses to odors, measured at the population level, tend to be spatially heterogeneous in the vertebrates that have been studied. These response patterns vary between odors but are similar across subjects for a given stimulus. However, few species have been studied making functional interpretation of these patterns problematic. One proximate explanation for the ...
