Magnetic‐Nanoparticle‐Based Dispersive Micro‐Solid Phase Extraction for the Determination of Crystal Violet in Environmental Water Samples

Abstract

In present study, a rapid and simple method based on ultrasonic‐assisted magnetic dispersive micro‐solid phase extraction (MD‐μ‐SPE) using magnetic ZnFe2O4‐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.

Zinc Oxide Nanomaterial‐Based Dispersive Solid Phase Extraction for the Trace Determination of Gold in Flash Gold Plating Solution Samples using Flame Atomic Absorption Spectrophotometry

“…A proper desorption solvent should elute target analyte from the adsorbent in small volumes [35] . The desorption of analyte(s) from the sorbent material surface with the help of a suitable solvent is known to be the last step of the solid phase extraction procedure.…”

Synthesis of magnetic date stone biochar for solid phase extraction of NSAIDs from water samples

“…Among these methodologies, the use of experimental designs for exploratory and optimization purposes has been reported in the literature. [20][21][22][23] The use of this strategy enables obtaining the maximum information with a reduced number of experiments that need to be carried out, in a shorter time and that can minimize reagent consumption. In addition, this approach can generate mathematical models that allow estimating the relevance of the factor and their interaction effects on the processes.…”

“…Several techniques exist for determining dyes present in different samples, e.g., high-performance liquid chromatography-ultraviolet (HPLC–UV), electrochemistry, and spectrophotometry 11 – 16 . Good selectivity, easy operation, low operating costs, and the ability to determine a wide range of materials in various fields are the main advantages of the spectrophotometry method over the other methods 17 , 18 .…”
