Abstract
Detection of pesticides in environmental matrices is neither for the modern analytical chemistry routine operation. It can be used, among others, to reveal their behavior in the environment. Electrochemical separation of chemicals is a powerful innovative tool that can extend the range of hyphenation methods in combination with mass spectrometry. Applicability of newly developed electrochemical separation using silver ions is based on high reactivity of nascent silver ions and on the high affinity of Ag+ to small ligands containing N. This group also includes the triazole fungicides, e.g. cyproconazole (Cyp). In this case, the generated Ag+ subsequently forms complex [Ag(Cyp)]+, detectable by electrospray ionization mass spectrometry. The newly developed method of separation prior ESI MS generally relates to (i) the detection of metal complexes with pesticides, (ii) the trace analysis of pesticides in environmental matrices, and (iii) the determination of the complexes stability and stoichiometry
