Cloud point extraction associated with differential pulse voltammetry: preconcentration and determination of trace uranyl in natural water

A procedure for electroanalytical determination of the uranyl ions pre-concentrated from natural water by cloud point extraction (CPE) was developed in this work. The CPE parameters, such as surfactant concentration,...

Cloud Point Extraction with Liquid Ion Exchange for Separation and Determination Magnesium (II) as anion

Liquid Ion Exchange joined with Cloud point extraction methodology was used for the separation of Magnesium (II) from aqueous and determine whereas 10 mL aqueous solution that contains 50 µg Mg2+ ion is complex with 1×10-3M 8-Hydroxy quinoline (8-HQ) at a suitable basic medium it well give higher extraction efficiency at optimum conditions, needs heating the aqueous solution in suitable temperature degree for enough time to form a cloud point layer (CPL). Therefore, the optimum conditions that yielded the good CPL have a small aggregation volume which is appropriate for continuing the ion pair association Complex between Magnesium ion and 8-Hydroxy quinoline.
