Flame Atomic Absorption Spectrometric Palladium Aqueous Samples Preconcentration Nanoparticles of γ-Alumina Functionalized Pyridine Groups
2010/9/20
A new solid phase, nanoparticles of alumina functionalized with pyridine groups, was synthesized and used for extraction and preconcentartion of palladium(II) ions from some water samples. The effects...
New Polyamides Derived from 2,5-Bis[(4-carboxyanilino) carbonyl] Pyridine and Hydantoin Derivatives: Synthesis and Characterization
Polyamides, pyridyl moiety hydantoin derivatives direct polycondensation
2010/4/16
We synthesized 2,5-bis[(4-carboxyanilino) carbonyl] pyridine (4) as a new monomer containing pyridyl moiety by using a 2-step reaction. At first 2,5-pyridine dicarboxylic acid (1) was converted to 2,5...
