Vortex Assisted Liquid–Liquid Microextraction Using Triton X‐114 for Ultratrace Cadmium Prior to Analysis

Abstract: Research ArticleVortex Assisted Liquid-Liquid Microextraction Using Triton X-114 for Ultratrace Cadmium Prior to Analysis A vortex-assisted liquid-liquid microextraction method coupled to micro-sample injection flame atomic absorption spectrometry for cadmium (Cd) determination in water samples, phenomena was established through phase separation of ionic surfactant in aqueous samples. The ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate [C 4 MIM][PF 6 ] was used as an extractant, while using Trito… Show more

“…For a wet acid digestion procedure, SRM 1570A spinach leaves, and food samples (0.2 g) were treated with 2.0 mL of a mixture of concentrated HNO 3 -H 2 O 2 (2:1, v/v) into the beaker and kept at room temperature for 10 min, then heated on an electric hot plate until semidried mass was obtained. Digested semi-mass samples were dissolved in 5.0 mL of deionized water and filtered through a cellulose membrane filter of 0.45 μm pore size [5]. Then, the developed VA-IL-DLLME procedure was satisfactorily applied to the samples.…”

“…Cadmium was categorized as a carcinogen compound to humans and a wide variety of chronic problems in liver, kidneys, renal, and lungs were caused by high exposure to cadmium [2]. Therefore, the estimation of trace Cd 2+ in different types of various samples is a very important objective for chemists using effective methods [3][4][5]. Trace quantities of Cd 2+ in real samples are less than the detection limit of some instruments such as flame atomic absorption spectrometry (FAAS) or GF-AAS and coexisting ion interference is two limitations in estimations [6][7][8].…”

“…The water samples were collected into polyethylene plastic bottles (1.5 L capacity) which were previously soaked in 10% nitric acid for 24 hours and rinsed with ultrapure water before use. All water samples were filtered through a 0.45 µm pore size cellulose nitrate membrane filter (Millipore Corporation, Bedford, MA, USA) and stored in a refrigerator at 4 °C (29).…”
