The adsorption of isonicotinamide showed a considerable alteration on both Si-OH stretching and deformation peaks of loughlinite structure. Spectroscopic results indicate that adsorbed isonicotinamide molecules onto loughlinite are coordinated to surface silanol groups and/or Lewis acidic centers by H-bonding interaction through pyridine ring nitrogen lone pairs. The amino nitrogen is found to be relatively in active to adsorbing sites.en-USAdsorptionClaysIR spectroscopyIsonicotinamideLoughliniteSepioliteHalide-ComplexesMontmorillonitePicolinamideNicotinamideIntercalationAnatoliaArticle3443611000113443611000112-s2.0-849043248952-s2.0-84904324895
