Abstract
|
|
|
|
Simultaneous analytical method has developed for the determination of anion biocides in soil by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Chlorite and chlorate in soil were extracted with pure water, and cyanuric acid and sodium dodecylbenzenesulfonate (Na-DBS) were extracted with mobile phase (0.25 mM ammonium formate in 20 mM formic acid : acetonitrile (1:1)). The extract was injected into the LC-MS/MS system after filtration. The method detection limits in this study were 0.04 mg/kg for chlorite, 0.04 mg/kg for chlorate, 0.27 mg/kg for cyanuric acid, and 0.05 mg/kg for Na-DBS, respectively. The method was applied to the analysis of 50 soil samples collected from 40 sites sprayed with biocides and 10 background sites. As a result, anion biocides were not detected in all sites.
