AI Article Synopsis
- A new method using liquid chromatography-electrospray ionization mass spectrometry (LC/ESI/MS) has been developed to detect 5 triazine herbicides and 12 of their degradation products in environmental water samples.
- The extraction of pesticides from water involved two types of solid phase materials: styrene-divinylbenzene copolymer and graphitized carbon black, with acetone and methanol used as desorption solvents, respectively.
- The method demonstrated good performance with recovery rates between 73% and 111% and limits of detection ranging from 0.2 to 28 ng/l, and it was successfully tested on various ground water samples.
Article Abstract
A method for the determination of 5 triazine herbicides and 12 degradation products in environmental water samples using liquid chromatography-electrospray ionization mass spectrometry (LC/ESI/MS) has been developed. The pesticides in water were extracted with two types of solid phase: a styrene-divinylbenzene copolymer and a graphitized carbon black. Desorption solvents for the extracted compounds were acetone for the styrene-divinylbenzene copolymer and methanol for the graphitized carbon black. Overall recoveries from ground water and river water ranged from 73% to 111%. The limits of detection (LODs) were 0.2 to 28 ng l(-1). This method was applied to several ground water samples.
