Under the optimal conditions, good linearities were obtained in the range of 5~100μg/L with correlation coefficients greater than 0.995. The limits were 1.16~2.88μg/L. The relative standard deviations ranged from 7.71% to 26.5%, and the recoveries were 52.3%~129% . The results showed that the current method could satisfy the demand of emergency monitoring. %R %U http://www.hjjkyyj.com/hjjkyyj/ch/reader/view_abstract.aspx %1 JIS Version 3.0.0
