Sorption and permeation of aqueous picolines in elastomeric membranes
Journal of Membrane Science, 1994 Separation of β- and γ-picolines from water using elastomeric membranes has been studied. PDMS and EPDM membranes were found to afford separation with good selectivity and flux over the entire concentration range.

Immunobiology of Picolinic Acid
1996Exposure of various cell types to IFN results in increased enzymatic activities leading to the breakdown of tryptophan and evidence exists to suggest that the catabolism of tryptophan may be connected to the biological effects of interferon (Carlin et al., 1989.

Simulation Study of Dissociation Extraction in Separation of 3-picoline and 4-picoline
2009 WRI World Congress on Computer Science and Information Engineering, 2009The two phases and multi-component system after the addition of the extractant was analyzed in detail?and a model was established by which the number of equilibrium stages for a given separated goal may be determined with stage-to-stage calculation. The experimental conditions were optimized by the results of the orthogonal test, and along with the ...
