Indirect quantification of trace levels cyanide in environmental waters through flame atomic absorption spectrometry coupled with cloud point extraction
(2013)
Cloud point extraction (CPE) has been used for the preconcentration and indirect quantification of cyanide after the formation of a ion-associate complex with 3-amino-7-diethylamino-8,9-benzo-2-phenoxazine chloride (Nile ...
A fast and reliable method for quantitative determination of total mercury in vegetables
(2013)
A cloud-point extraction (CPE) process using the nonionic surfactant, polyethylene glycol tert octylphenyl ether (Triton X-114) was employed for determination of Hg(II) ions in aqueous solutions. The method is based on the ...
Determination of trace cadmium in nonalcoholic beverages by coupling cloud point extraction with spectrophotometry
(2013)
A cloud-point extraction (CPE) process using the nonionic surfactant, Triton X-114 to extract Cd(II) ions from aqueous solutions was investigated. The method is based on the ion-pairing reaction of Cd(II) with Victoria ...
A reliable method of quantification of trace copper in beverages with and without alcohol by spectrophotometry after cloud point extraction
(2013)
A new cloud point extraction (CPE) method was developed for the separation and preconcentration of copper (II) prior to spectrophotometric analysis. For this purpose, 1-(2,4-dimethylphenyl) azonapthalen-2-ol (Sudan II) was ...
Cloud point extraction of trace cyanide from environmental waters for indirect flame atomic absorption spectrometric determination
(2013)
A method has been developed for indirect determination of cyanide in environmental waters based on cloud point extraction (CPE), preconcentration and determination by flame atomic absorption spectrometry (FAAS). The method ...
A reliable determination of zinc levels in beverages with and without alcohol by flame atomic absorption spectrometry after cloud point extraction
(2013)
Cloud point extraction (CPE) has been used for the preconcentration and quantification of zinc after the formation of a stable complex with N-phenylbenzohydroxamic acid (PBHA) at pH 9.0 and analysis by flame atomic absorption ...
Determination of low levels of molybdenum (VI) in food samples and beverages by cloud point extraction coupled with flame atomic absorption spectrometry
(2013)
Cloud point extraction (CPE) was used for the preconcentration of molybdenum (Mo), after the formation of a complex with Victoria pure blue BO (VPB+) in presence of excess thiocyanate and cetylpyridinium chloride (CPC) at ...
