A homogeneous liquid–liquid microextraction based on temperature-controlled ionic liquid for the accurate and selective determination at low levels of zineb residues in foodstuff by using experimental design

A simple and homogeneous green liquid–liquid microextraction based on temperature-controlled ionic liquid (IL) process was developed for the selective extraction spectrophotometric analysis of zinc (II) ethylenebis (dithiocarbamate) (zineb) from different foodstuff samples including rice, wheat, corn, oat, cabbage, potato, tomato grain. The effect various parameters like pH, IL dose, temperature, ultrasound time foreign ions were studied. proposed method exhibited good precision accuracy recovery zineb. spiked with 50 150 µg zineb checked its effects LOD 9.1 ng mL−1, LOQ 30 linear range 30–600 enhancement factor 152 RSD % values found 3.2%. multivariate statistical also carried out to interpret data. factorial design used examine impacts variables foodstuff.
