Determined on Atrazine and Carbaryl in Surface Water by High Performance Liquid Chromatography

The method was proposed for the simultaneous determination of atrazine and carbaryl in surface water by reverse-phase high performance liquid chromatography.The recovery rates of atrazine and carbaryl were respectively 74.2%~118%、77.4%~103%,and the detection limits of atrazine and carbaryl were respectively 0.006 μg/L、0.036 μg/L.The results showed that the method was suitable for determining atrazine and carbaryl in surface water.The water sample having the high concentration,it could be filtrated,then injected and determined directly.
