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 ...
