Photocatalytic TiO2-catalyzed degradation of bromophenol blue-mediated Mo(VI)-peroxo complexes inthe presence of SDS
(DESALINATION PUBL, 2016)
In the present study, the photocatalytic TiO2-catalyzed degradation of bromophenol blue (BPB)-mediated Mo(VI)-peroxo complexes in the presence of sodium dodecyl sulfate (SDS) under UV irradiation was investigated. The ...
Simple and fast spectrophotometric determination of low levels of thiabendazole residues in fruit and vegetables after pre-concentration with ionic liquid phase microextraction
(TAYLOR & FRANCIS LTD, 2018)
There is a great importance of monitoring thiabendazole (TBZ) residues in fruits and vegetables to ensure food safety. Therefore, a new ionic liquid (IL) phase microextraction method using IL, 1-butyl-3-methylimidazolium ...
Preconcentration of sulfite from food and beverage matrices by ultrasonic assisted-cloud point extraction prior to its indirect determination by flame atomic absorption spectrometry
(ROYAL SOC CHEMISTRY, 2016)
The additives used in foods and beverages may be harmful to human health. Thus, there is an increasing demand for analytical methods that allow the reliable identification and quantification of high-risk substances. In ...
Extraction and reliable determination of acrylamide from thermally processed foods using ionic liquid-based ultrasound-assisted selective microextraction combined with spectrophotometry
(TAYLOR & FRANCIS LTD, 2018)
Acrylamide (AAm) is a carcinogenic chemical that can form in thermally processed foods by the Maillard reaction of glucose with asparagine. AAm can easily be formed especially in frequently consumed chips and cereal-based ...
Innovative and practical deep eutectic solvent based vortex assisted microextraction procedure for separation and preconcentration of low levels of arsenic and antimony from sample matrix prior to analysis by hydride generation-atomic absorption spectrometry
(ELSEVIER SCI LTD, 2019)
Considering the negative impacts on human health and the environment, determinations of arsenic (As) and antimony (Sb), is of unquestionable importance. The present study describes the development of innovative and practical ...
A new ultrasonic-assisted cloud-point-extraction procedure for pre-concentration and determination of ultra-trace levels of copper in selected beverages and foods by flame atomic absorption spectrometry
(TAYLOR & FRANCIS LTD, 2015)
A new ultrasonic-assisted cloud-point-extraction (UA-CPE) method was developed for the pre-concentration of Cu(II) in selected beverage and food samples prior to flame atomic absorption spectrometric (FAAS) analysis. For ...
Vortex assisted-ionic liquid dispersive liquid-liquid microextraction and spectrophotometric determination of quercetin in tea, honey, fruit juice and wine samples after optimization based on response surface methodology
(PERGAMON-ELSEVIER SCIENCE LTD, 2019)
The aim of our study is to develop a new vortex assisted-ionic liquid dispersive liquid-liquid microextraction (VA-IL-DLLM ) method for preconcentration and determination of the quercetin in tea, honey, fruit juice and ...
Surfactant-sensitized spectrophotometric determination of Hg(II) in water samples using 2-(2-thiazolylazo)-p-cresol as ligand and cetylpyridinium chloride as cationic surfactant
(SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY-TUBITAK, 2012)
A new, reliable, surfactant-sensitized method is described for the spectrophotometric determination of total and dissolved inorganic mercury at trace levels. The method is based on the ternary complex formation of Hg(II) ...
Microextraction and preconcentration of Mn and Cd from vegetables, grains and nuts prior to their determination by flame atomic absorption spectrometry using room temperature ionic liquid
(ELSEVIER SCIENCE BV, 2017)
In this paper, a new and eco-friendly vortex-assisted dispersive liquid-liquid microextraction (VA-DLLME) procedure based on application of the room temperature ionic liquid (RTIL) 1-butyl-3-methylimidazolium chloride, ...
