Abstract

Abstract: In present study, a rapid and simple method based on ultrasonic‐assisted magnetic dispersive micro‐solid phase extraction (MD‐μ‐SPE) using magnetic ZnFe2 O4 ‐ZnS nanocomposites has been proposed for the determination of crystal violet (CV) in environmental water samples. To increase the extraction efficiency, the affecting factors on the ultrasonic‐assisted magnetic dispersive micro‐solid phase extraction method were investigated and optimized by Taguchi method, artificial neural network (ANN), and response surface methodology (RSM). For proposed method, the crystal violet was selected as target dye. Under optimal conditions, the limits of detection were obtained 25 ng mL −1 and the calibration curve showed linearity in the range of 100–600 ng mL −1 . The good extraction efficiency obtained indicates that the proposed MD‐μ‐SPE possesses a good potential for the determination of CV in environmental water samples.
