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.
Highlights
The polar pesticides as simazine, atrazine, thiodicarb, pyrimicarb, carbofuran, carbaryl, isoprocarb and diuron have been widely used due to their properties
A volume of 200 mL filtered surface water sample was loaded through 200 mg solid phase extraction (SPE) Oasis HLB cartridge that was previously conditioned with 3 mL of MeOH and 3 mL of ultrapure water
Surface water and sediment were spiked with eight pesticides extracted by the methods presented and analyzed by RP – HPLC
Summary
The polar pesticides (logKow 1.6 – 2.8) as simazine, atrazine (triazine herbicides), thiodicarb, pyrimicarb, carbofuran, carbaryl, isoprocarb (carbamate insecticide) and diuron (phenylurea herbicides) have been widely used due to their properties. A volume of 200 mL filtered surface water sample was loaded through 200 mg SPE Oasis HLB cartridge that was previously conditioned with 3 mL of MeOH and 3 mL of ultrapure water.
