    Abstract: The use of lignocellulosic materials for oil sorption from aqueous medium has directed attention to acetylation as a means of increasing the hydrophobicity of these materials. In this paper, acetylation of Cucumeropsis mannii seed shell, a readily available agricultural waste, was studied. Effects of different acetylation conditions on the extent o... Show More

    Abstract: Two Schiff bases (H2L), derived from o-vanillin and nicotinic hydrazide, and its complexes with some lanthanides (Y, Ce, Yb, Pr, Gd and Tb) have been synthesized. These compounds have been characterized by means of elemental analysis, UV–Vis spectroscopy, FTIR spectroscopy, 1H and 13C NMR (for H2L), molar conductance and room temperature magnetic m...
