U.V Spectroscopic study of Benzylidine p-toluenesulphonomide Schiff- bases in absolute methanol – Direct determination of trace amounts
JOURNAL OF EDUCATION AND SCIENCE,
2012, Volume 25, Issue 4, Pages 12-26
The study including preparation of Schiff's Bases compounds, Benzylidine p-toluenesulphonamide (I), p-nitrobenzylidine-p-toluenesulphonamide (II), 1,6-dichlorobenz-ylidine p-toluenesulphonamide (III), 3,4-dimethoxybenzylidine p-toluenesulphonamide (IV) and have been studied by U.V spectrophotometry in absolute methanol which gives bands at (236 nm) for compound (I), (266 nm) for compound (II), (236 & 304nm) for compound (III) and (236, 274 & 308nm) for compound (IV).
The direct determination limit was estimated through the plot of the molar concentration against the absorbance and R2, RSD and max for each was calculated.
