A Novel Selective Deep Eutectic Solvent Extraction Method for Versatile Determination of Copper in Sediment Samples by ICP-OES

Abstract

In the present study, a simple, mono step deep eutectic solvent (DES) extraction was developed for selective extraction of copper from sediment samples. The optimization of all experimental parameters, e.g. DES type, sample/DES ratio, contact time and temperature were performed with using BCR-280 R (lake sediment certified reference material). The limit of detection (LOD) and the limit of quantification (LOQ) were found as 1.2 and 3.97 µg L, respectively. The RSD of the procedure was 7.5%. The proposed extraction method was applied to river and lake sediments sampled from Serpincik, Çeltek, Kızılırmak (Fadl and Tecer region of the river), Sivas-Turkey.

Application of Extraction and Determination Based on Deep Eutectic Solvents in Different Types of Environmental Samples

“…Following the extraction of solid samples, the suspensions obtained by centrifugation usually need to be filtered before entering the instrument for analysis. The DES composed of choline chloride and oxalic acid was used as a solvent for extraction of As, Cr, Mo, Sb, Se, and V in real soil samples [79] and Cu in sediment samples [80]. Compared with the results determined using the conventional acid digestion method, the method was found to be accurate, precise, and eco-friendly.…”

“…Many methods were used to determination copper such as colorimetric [3,4], sensors [5,6], electrochemical [7][8][9][10], graphite furnace atomic [11], spectrophotometric [12,13], and liquid-liquid microextraction [14]. Solvent extraction method coupled with ICP-OES [15], and determination of serum copper using ICP technique [16]. Most of the methods are expensive or low selectivity and sensitivity.…”

“…Deep eutectic solvents (DES) are considered as green solvents and have been utilized by many scientists to solve different environmental problems 19–21 . Due to the biocompatible characteristics of DES, it is widely being considered as a green medium for various applications, including bioengineering, phase separation, biocatalysis, synthesis for electrochemical, and electropolishing has been introduced 22,23 . Thus, green chemistry aims to plan an environmentally compassionate chemical process and synthetic strategies to minimize the utilization of the toxic chemical at any stage of the textile industries.…”
