“…Conostan element blank oil (LOT 35) was used in order to find limit of determination (LOD) and limit of quantification (LOQ) of the method. The Schiff base, N,N'-bis(5-methoxy-salicylidene)-2-hydroxy-1,3-propanediamine (5MSHP) shown in Fig.1 was synthesized and characterized in our previous work (Köse Baran and Bağdat Yaşar, 2012b). Schiff base stock solution was prepared in 18% (v/v) ethanol-water mixture and stored in polyethylene containers at room temperature.…”

A new method for the determination of copper in edible oils was suggested. The proposed method is based on the extraction of copper with N, N′-bis(5-methoxy-salicylidene)-2-hydroxy-1,3-propanediamine (5MSHP) followed by flame atomic absorption spectrometry measurement. Firstly, copper complex with 5MSHP was investigated spectrophotometrically. After the analytical properties of the complexation had been defined, optimization of the extraction conditions of copper from oils was performed using a central composite design. Optimal conditions for the extraction of copper with 5MSHP were found to be 26.7℃, 1.

“…Traditional analytical methods to determine trace Fe in vegetable oils are mainly based on the use of instrumental techniques, such as flame atomic absorption spectrometry (FAAS), 9,10 electrothermal atomic absorption spectrometry (ETAAS), 11 inductively coupled plasma optical emission spectrometry (ICP OES) 2,12 and inductively coupled plasma mass spectrometry (ICP-MS). 13 In most instances, these techniques have been applied in association with various types of sample pretreatments before the analysis, aimed to reduce matrix and spectral interferences and increase the availability of the trace metals for determination in viscous liquid samples containing a high organic content, such as vegetable oils.…”

“…14,15 Direct analysis of vegetable oils for the determination of Fe or other metals is not a simple task. The difficulty is mainly due to the low levels of Fe in vegetable oils, as well as to the other problems caused by matrix interferences, 2,9,16 such as the high organic content and high viscosity of these matrices. 2 These matrix properties can cause destabilization of the inductively coupled plasmas and flames employed as atomization systems in ICP and FAAS techniques, respectively.…”

This work proposed a novel, relatively low-cost and rapid analytical method using microemulsion as sample preparation to determine iron (Fe) in vegetable oils by flame atomic absorption spectrometry technique (FAAS). The vegetable oil microemulsions were obtained by mixing appropriate proportions of the crude and refined vegetable oil, Triton ® X-100, 1-propanol and nitric acid 50% (v v -1 ). Moreover, an external calibration method was established using aqueous Fe standards instead of expensive and unstable organometallic standards. The limits of detection and quantification were 0.40 and 1.3 mg kg -1 of oil, respectively. The accuracy was checked by recovery studies (with recoveries ranging 84-105%) and by Fe determination in digested vegetable oil samples by inductively coupled plasma optical emission spectrometry (ICP OES) as comparative procedure. The proposed analytical method was efficient to determine Fe in crude and refined vegetable oils from various vegetable sources, besides being suitable for routine analyses due to its simplicity.

In the present work, a new and simple Schiff base‐assisted extraction strategy for Ni and Zn from an edible oil matrix with subsequent determination using a flame atomic absorption spectrometer was suggested. According to the green approach, laborious sample‐pretreatment procedures were eliminated via complexation of the analytes with N,N′‐bis(4‐methoxysalycylidene)‐2‐hydroxy‐1,3‐propanediamine (4MSHP) and transferred from the oil phase to the aqueous phase. The complexation properties of 4MSHP, Ni, and Zn were investigated using UV–vis spectrophotometry. The experimental conditions that affect the extraction efficiency were optimized using central composite design. The optimum conditions for the extraction of Ni and Zn were as follows: a volume to oil mass ratio of 0.83 to 1.31 mL g−1 of 4MSHP solution; 62.3‐ and 50.6‐min, stirring time; 27.3 and 31.1 °C, temperature, respectively. The detection limits (3sbm−1) were 0.41 μg g−1 for Ni and 0.16 μg g−1 for Zn. Validation of the suggested work was performed by the analysis of organometallic standard‐doped n‐hexane solutions as certified reference materials under the optimum experimental conditions. The recovery percentages were warranted the accuracy and found as 98.2 ± 1.8% for Ni and 99.8 ± 1.2% for Zn. In addition, relative SD values were below 5% for both the analytes. The Student's t‐test showed that there was no significant difference between the found and doped amount of analytes at 95% confidence level. The features such as the detection technique, cheapness, eco‐friendly solvent usage, and practicality were better compared to the literature.
