Abstract
A U.V. spectrophotometric study of furan-2-carboxaldehyde tiosemicarbazone was performed. It has an only maximum at 316 nm and is stable for secen days. Absorbance doesn't vary in a range of pH from 2 to 10. Lambert-Beer's law is obyed for furfural concentrations between 1.1O-5 M and5.1O-5 M. Molar absortivity is E316=29500 M-1 L cm-1.
