| Notes | A sensitive LC-MS/MS method for simultaneously analyzing atrazine and its 6 metabolites in cattle drinking water was established. The samples were enriched and purified by MCX solid-phase column, determined by LC-MS/ MS, and quantified by outer standard. The results showed that the linear range spanned from 0.4 to 100 μg/L with correlation index r2 greated than 0. 99. At the concentration range of 0. 03 ~ 3 μg/L, except the recovery of des isopropyl-2-hydroxy was 64. 17 %, others were 71.31% ~ 116.67 % with relative standard deviations ranging from 0. 97% to 12.03%. The limits of detection （LOD） of 7 substances analyses were 0.1 μg/L. Those indicated the method was rapid, cost-effective and suitable for water sample analysis.
