Me-BTABr reagent in cloud point extraction for spectrometric determination of copper in water samples

A new preconcentration method using cloud point approach is proposed for copper determination. The reagent 2-[2-(6-methyl-benzothiazolylazo)]-4-bromophenol (Me-BTABr) was used as a complexing agent and Triton X-114 was added as a surfactant. After phase separation, dilution of the surfactant-rich ph...
