Extraction, preconcentration and spectrophotometric determination of trace levels of thiosulfate in environmental waters
(Springer Verlag, 2017)
In the existing study, a new vortex-assisted cloud point extraction (VA-CPE) method was developed for determination of low levels of thiosulfate in environmental waters at 632 nm by spectrophotometry. The method is selectively ...
Preconcentration and determination of trace vanadium(V) in beverages by combination of ultrasound assisted-cloud point extraction with spectrophotometry
(Slovensko Kemijsko Drustvo, 2018)
A novel ultrasound assisted-cloud point extraction method was developed for preconcentration and determination of V(V) in beverage samples. After complexation by pyrogallol in presence of safranin T at pH 6.0, V(V) ions ...
Determination of trace cadmium in nonalcoholic beverages by coupling cloud point extraction with spectrophotometry
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 ...
