Abstract

A new coprecipitation procedure was improved for preconcentration-separation and detection of trace propineb. In order to coprecipitate propineb, 8-hydroxyquinoline (8HQ) and copper (II) were used as a precipitating agent and a carrier element, respectively. Using the stoichiometric relationship with zinc, propineb was determined. The critical parameters on the quantitative recoveries of analyte such as pH, mass of precipitating agent, mass of carrier element, and sample volume were studied. The influences of the matrix components were also tested. The preconcentration factor was 80. The limit of detection (LOD), and the limit of quantification (LOQ) for propineb were 0.114 mg L−1 and 0.38 mg L−1, respectively. Copper(II)-8-hydroxyquinoline coprecipitation was applied to determine propineb in vegetable and fruit samples from Kayseri-Turkey with satisfactory results. Flame atomic absorption spectrometry (FAAS) was utilized for measurements of model and real sample solutions.
