Determination of sunset yellow (E110) in foodstuffs and pharmaceuticals after separation and preconcentration via solid‐phase extraction method

Abstract

Summary The two novel preconcentration and separation methods based on adsorption onto Amberlite XAD‐1180 and Amberlite XAD‐16 polymeric resins for spectrophotometric determination of sunset yellow dye were developed. The parameters, affecting the quantitative recovery, including pH, sample and eluent flow rates, eluent type, sample volume, were investigated and optimised. The interference effects of some cations, anions and widely used dye were also studied. At the optimum conditions, detection limits of the methods were found as 2.0 and 1.6 μg L−1 for Amberlite XAD‐1180 and Amberlite XAD‐16 resins, respectively. Linear dynamic ranges of the methods were obtained in the range of 0.2–50.0 and 0.2–20.0 μg mL−1 for Amberlite XAD‐1180 and Amberlite XAD‐16 resins, respectively. The relative standard deviations were below than 7% and 5% for Amberlite XAD‐1180 and Amberlite XAD‐16 resins, respectively. The determination of dye was performed at 483.0 nm using spectrophotometry. Validations of the methods were performed comparatively with determination of the sunset yellow content of some foodstuffs and pharmaceuticals.

Optimization of solid phase dispersive field‐assisted ultrasonication for the extraction of auramine O and crystal violet dyes using central composite design

“…Dyes discharged from the dyes manufacturing, textile and paper industries wastewaters are main organic contaminations and biggest contributors to aquatic pollution . Most of them are highly visible undesirable even at low concentrations and accomplished hazards and difficultly in water as well as majority are toxic, non‐biodegradable, and even teratogenetic, mutagenic, carcinogenic, which create the serious threats to human health . Therefore, the dyes must be efficiently detected before entered into human health even at lower concentration from the discharged wastewater, organism, atmosphere and soil.…”

“…[4,5] Most of them are highly visible undesirable even at low concentrations and accomplished hazards and difficultly in water as well as majority are toxic, non-biodegradable, and even teratogenetic, mutagenic, carcinogenic, which create the serious threats to human health. [6][7][8] Therefore, the dyes must be efficiently detected before entered into human health even at lower concentration from the discharged wastewater, organism, atmosphere and soil. Until now, the liquid-liquid and solid-phase extraction widely used as sample pretreatment techniques for determination of dyes from wastewater and food samples.…”

Application of a Novel Micro-Cloud Point Extraction for Preconcentration and Spectrophotometric Determination of Azo Dyes

“…10 Therefore the importance of their removal/decolorization [11][12][13] and their determinations [14][15][16][17] in environmental samples is obvious. Many analytical methods have been suggested for extraction and determination of azo dyes such as cloud point extraction (CPE), [18][19][20] liquid-liquid extraction (LLE), 21,22 liquid phase microextraction (LPME), 23 solid phase extraction, [24][25][26] solid phase microextraction, 27 and molecularly imprinted solid phase extraction. 28 Nowadays, based on principals of green chemistry, liquid phase microextraction techniques have become very popular and many new and microextraction techniques have been developed based on classical liquid-liquid extraction.…”

Solid-phase extraction of explosive nitramines on macroreticular polymers modified by freezing with water or acetone

“…The present‐day polymeric beds of the XAD kind, however, despite their limitations, continue to be successfully used in SPE . They are equally often employed as a convenient base for preparation of chemically modified adsorbents, for example, chelating resins for the determination of heavy metals or on introduction of amino groups into the aromatic rings that enable the determination of fluoride ions .…”
