A solid phase extraction GC MS method with high selectivity was used to determine nonylphenol (NP) in three gorges (Yangtze River and Jialing River) aquatic environment. The detected results showed that the river water and its concentration ranged from 0 02 to 6 85?μg/L with different sampling sites and seasons,after treatment NP in waterworks, was removed more than 60% and the residual NP was in a range from under detected limit to 2 73?μg/L. By the analytical method, the recoveries for st...
