I am working on detection of pesticides (especially Organochlorines) in river water. So I am interested to know that in between QuEChERS and SPE which extraction technique provides better detection. Thanx in advance .
Dear Vineet in river's water pesticides are usually at low concentrations (ppb or ppt) so you need a method that allows extraction from large water volumes (e.g. 1L). To my opinion SPE is your only choise.
Dear Vincent, I agree with Nikolaos, you will need SPE.
In an earlier work we determined pesticides in surface and drinking water via SPE:
Pham Van Toan,, Zita Sebesvaria, Melanie Bläsing, Ingrid Rosendahl, Fabrice G. Renaud Pesticide management and their residues in sediments and surface and drinking water in the Mekong Delta, Vietnam. Science of the total environment
Here we modified the method of
Laabs V, Wehrhan A, Pinto A, Dores E, Amelung W. Pesticide fate in tropical wetlands of
Brazil: an aquatic microcosm study under semi-field conditions. Chemosphere2007;67:975–89.
Best wishes from Bonn,
Melanie
