Abstract:
Objective To establish a polarographic method for detecting fluoroacetamide.Methods On the condition of strong basic solution with high temperature fluoroacetamide was decomposed to form a decomposed product ALC-La-F - complex.In a pH4.90buffer solution containing KNO 3 and hexamethylenetetramine,the decomposed product was determined with com-plex-adsorptive wave at-0.67V by polarography.Re sults The detection limit and linear range of the method was2.0?10 -8 mol/L and5.0?10 -8 -1.2?10 -6 mol/L respectively.The regressive equation was y=3.49x+0.042with a correlation coefficient r=0.9996.The method had been applied to the determination of fluoroacetamide in wheat flour samples satisfyingly.Conclu-sion This method was simple and suitable for the determination of fluoroacetamide in flour.
