Cloud point microextraction (CPME) with Triton X-114, as a nonionic surfactant, was applied for the extraction of zinc ethylene-1,2-bisdithiocarbamate (zineb) prior to its determination by flame-atomic absorption spectrometry (FAAS). The optimum CPME conditions were obtained with 250 µL of Triton X-114 at a cloud point temperature of 30 °C in 20.0 mL of the sample solution whose pH had been adjusted to 7.00. Zineb was monitored at a wavelength of 213.0 nm. The limits of detection were found to range between 13.0 and 25.0 ng mL−1 and the coefficients of determination (R2) of the calibration graphs were between 0.9975 and 0.9994. The developed CPME-FAAS method was applied to extract and determine in food and environmental samples with percentage relative recoveries ranging from 90.6 to 105.4% with percentage relative standard deviations (%RSD) less than 7.5%.
