Detection and discrimination of organophosphorus pesticides in water by using a colorimetric probe array

Abstract

[EN] Detection and discrimination of several organophosphorus pesticides in water using a colorimetric probe array containing twelve dyes has been achieved. A clear discrimination for malathion, leptophos, dichlorvos, dibrom and diazinon was observed. The array was used to determine the concentration of diazinon in orange leaves ; The financial support from the Spanish Government (project MAT2012-38429-C04), the Generalitat Valenciana (project PROM-ETEO/2009/016) and the Universitat Politecnica de Valencia (project ref. 2711) is gratefully acknowledged. SCSIE (Universidad de Valencia) is also acknowledged for all the equipment employed. ; Ferri, D.; Gaviña, P.; Costero, AM.; Parra, M.; Vivancos, J.; Martínez-Máñez, R. (2014).
