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
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 ...
Preconcentration and indirect quantification of trace nitrite, nitrate and total nitrite in selected beverage and milk samples using ion-pairing cloud-point extraction with acridine orange
(Academic Press Inc., 2018)
A new indirect preconcentration method was developed for micellar-sensitive detection of trace nitrite as analyte by spectrophotometry. It is based on selective ion-pairing complex formation of triiodide ion, I3 ? with ...
