| Abstract: | To determine the formaldehyde in aquatic products by dinitrophenyl hydrazine derivative -high performance liquid chromatography. It was performed on diamonsirC18 （5 μm,250 mm×4.6 mm） with a mixture of methanol - water （ volume ratio 5.5 ： 4.5 ） as mobile phase at the flow rate of 1.0 mL ·min^-1 and detected at 357 nm with the injection volume of 10 μL, The result showed the liner relationship is satisfactory in the range of 0. 0063 - 0. 1260 μg with the correlation coefficient of 0. 9991. The average recovery was 105%. This method is simple, accurate and valuable to determine the formaldehyde in aquatic products. |
