Multi-residue analysis of polar pesticides in surface water and sediment by high performance liquid chromatography

Abstract

We have successfully studied the analytical method of polar pesticides like carbofuran, pirimicarb, thiodicarb, atrazine, simazine, carbaryl, diuron, isoprocarb in surface water and sediment by HPLC-UV. The method could be applied to HPLC- MS. The stable recoveries ranged from 79 – 110 % with surface water and sediment samples. Especially, a cleanup procedure combined QuEChERS method and solid phase extraction has been developed to analyse these compounds in sediment, a very complex matrix.
