An Inexpensive and Sensitive Method for Speciative Determination of Sn(IV), Sn(II), and Total Sn as Sn(IV) in Selected Beverages by Micellar Improved Spectrophotometry
(2015)
In the present study, an inexpensive, selective, and micellar sensitive spectrophotometric method for Sn(IV) was developed at 537 nm. The method is based on the formation of ternary complex of Sn(IV) with tartaric acid and ...
Determination of total Sn in some canned beverages by FAAS after separation and preconcentration
(2015)
A micelle-mediated preconcentration method has been developed for determination of trace amounts of tin in canned beverage samples, which is widely used in food industry for packing, but its utilization is limited due to ...
Development of a simple, sensitive and inexpensive ion-pairing cloud point extraction approach for the determination of trace inorganic arsenic species in spring water, beverage and rice samples by UV-Vis spectrophotometry
(2015)
The determination of inorganic arsenic species in water, beverages and foods become crucial in recent years, because arsenic species are considered carcinogenic and found at high concentrations in the samples. This ...
A new cloud point extraction procedure for determination of inorganic antimony species in beverages and biological samples by flame atomic absorption spectrometry
(2015)
A new cloud-point extraction (CPE) for the determination of antimony species in biological and beverages samples has been established with flame atomic absorption spectrometry (FAAS). The method is based on the fact that ...
Quantification of 5-hydroxymethylfurfural in honey samples and acidic beverages using spectrophotometry coupled with ultrasonic-assisted cloud point extraction
(2015)
The simple, cost-effective and fast preconcentration method using ultrasonic-assisted cloud point extraction (UA-CPE) has been developed for determination of 5-hydroxymethylfurfural (5-HMF) by means of spectrophotometry. ...
A Novel Preconcentration Procedure Using Neutral Red as Ion-Pairing Reagent for Determination of Inorganic Dissolved Arsenic Species in Different Water and Beverages by Spectrophotometry
(2015)
In the current study, a new cloud point extraction (CPE) procedure was developed for the separation and preconcentration of inorganic soluble As species, As(III), As(V), and total As in water and beverage samples. Selective ...
Indirect Determination of Free, Total, and Reversibly Bound Sulfite in Selected Beverages by Spectrophotometry Using Ultrasonic-Assisted Cloud Point Extraction as a Preconcentration Step
(2015)
A new indirect ultrasonic-assisted cloud point extraction (UA-CPE) method has been developed for the determination of trace sulfite species by means of spectrophotometry. The method is based on either directly imide–bisulfite ...

A new micellar mediated cloud-point extraction procedure (CPE) has been developed for sensitive and selective determination of trace amounts of total iodine by means of indirect spectrophotometry. The method is based on ...
A simple, inexpensive and convenient procedure for determination of inorganic Sb species in milk and beverage samples in PET containers by flame atomic absorption spectrometry
(2015)
A simple and efficient Cloud Point Extraction (CPE) method has been proposed for separation and preconcentration of inorganic Sb species. The method is based on stable hydrophobic complex formation of Sb(iii and v) with ...
A new preconcentration procedure to quantify total acid hydrolyzed fluoride in selected beverages and foods by spectrophotometry
(2015)
A new micellar-mediated, cloud-point extraction (CPE) method has been developed for the quantification of trace levels of fluoride by means of spectrophotometry. The method is based on the selective ion association of ...
