Abstract
The CE has become one of the advantageous tools in fungicides analysis in complex matrices due to its simplicity and separation efficiency. The separation of a group of thee triazole (i.e. penconazole, tebuconazole, and cyproconazole) fungicides was achieved with CD-MEKC with anionic Sγ-CD as a selector at pH=4.8.
The background electrolyte consisted of TRIS phosphate buffer (50 mM) and 15 mM SDS. The separation was performed on uncoated fused silica capillary with 500/425 mm (total/effective) length under -15 kV separation voltage.
Achieved LOD values with this method were: 0.73; 1.88; 0.60; 1.18 (µmol/L) for penconazole, tebuconazole, cyproconazole A and B respectively.
