A Simple and Efficient Extraction Method for the Preconcentration of Copper in Tap Water and Linden Tea Samples Prior to FAAS Measurement

Abstract

In this study, a simple, low‐cost and eco‐friendly analytical method namely syringe assisted pipette tip dispersive solid phase extraction (SA‐PT‐DSPE) combined with slotted quartz tube‐flame atomic absorption spectrometry (SQT‐FAAS) system was presented for the determination of copper at trace levels in linden tea and tap water samples. Under the optimal experimental conditions, limit of detection (LOD) and quantification (LOQ) values obtained for the SA‐PT‐DSPE‐SQT‐FAAS system were calculated as 3.7 and 12.5 μg/L, respectively. The SA‐PT‐DSPE‐SQT‐FAAS system provided a 44.0‐folds improvement in detection power of the conventional FAAS. The recovery results for tap water samples were calculated close to 100 % via external calibration strategy. Negative matrix effects on the analyte were observed for linden tea samples. Therefore, recovery studies were performed by matrix matching calibration strategy and percentage recoveries were found to be between 88.0–102.0 % with low standard deviation values.

“…12 Among the aforementioned methods, FAAS is preferred by many research laboratories in heavy metal determination because of its outstanding features such as short analysis times, easy and inexpensive operation, and not requiring complicated mechanisms. 13 However, the FAAS system has critical limitations in the determination of analytes at trace levels, such as that approximately ten percent of the sample solution can be transported by the nebulizer to the atomizer and interference effects from the matrix. 14 Therefore, it is necessary to apply a suitable preconcentration method to minimize the effects of these disadvantages and increase device sensitivity.…”

Modelling the kinetics of direct Cu(II) adsorption on two porous resins modified with mussel-inspired chemistry

“…Thus, efficient methods are sought for the removal of copper from water resources, and different methods can be used for this purpose. Together with its simplicity, adsorptive removal offers inexpensive and efficient ways of metal removal [1][2][3][4][5]. Metal adsorption to surfaces may also be important in immobilization of ligands to surfaces [6] and in heterogeneous catalysis [7] processes.…”

Development of an innovative and original portable pipette with different filtration layers for water purification

“…Adsorption is the adhesion of a substrate in a gas or liquid phase to the functional group of the adsorbent surface through various intermolecular forces. This process continues until the adsorbent surface reaches maximum saturation [10]. Adsorbents are materials to which molecular species adhere to the surface and may be of synthetic origin.…”
