Aminotriazole is a polar and water-soluble organic pesticide and its preconcentration cannot be performed using either liquid-liquid extraction or solid-phase extraction with reversed-phase sorbents such as C,, silica, apolar copolymers or porous graphitic carbon. Aminotriazole can be ionised and it
