| Abstract: | A new,simple,quick and effective determination method of Acrylamide in water sample has been established.The compound in water sample(20ml) was reacted with KBr:KBrO3 solution and the Brominated derivatives was extracted with Ethyl actate∶Hexcane(9∶ 1,2.0ml),2.0μl of the extracted solution was injected on a SPB608(30m×0.53mm×0.50μm)capillary column and determined by GC-ECD.The average recoveries and relative standard deviations of Acrylamide were 95.4%~113%and less than 11.5%respectively.The detected limits were less than 0.05μg/L.The method is simple,fast,sensitive and accurate for Acrylamide determination of lots of water samples. |
