The photometric method was used for the determination of formaldehyde in wines.The conditions of determination was optimized.Its absorption reached maximum at 445nm,and a molar absorptivity e_(445)=4.75×10~(4)L/mol.cm.Linear relationship between the absorbance and the concentration of formaldehyde was found in the range of 0.02~0.10mg/25mL with a detection limit of 0.019mg/L.RSD's(n=7) found were…
