Extraction-Stripping Patterns during Co-Extraction of Copper and Nickel from Ammoniacal Solutions into Emulsion Liquid Membranes Using LIX 84I®
Extraction of nickel and its co-extraction with copper from ammoniacal media into emulsion liquid membrane systems (ELMs) was investigated using LIX 84I as the carrier. Measurement of the solute stripped in the internal phase of emulsion opened a new dimension in the study of the ELM extraction processes. The effect of operating parameters such as feed pH, initial feed concentration, and treat ...
متن کاملSpectrophotometric Determination of Copper and Nickel in Marine Brown Algae after Preconcentration with Surfactant Assisted Dispersive Liquid-Liquid Microextraction
A simple, fast and effective pre-concentration method for the determination of Cu (copper) and Ni (nickel) was developed using a Surfactant Assisted Dispersive Liquid-Liquid Microextraction (SA-DLLME) coupled by UV-Vis spectrophotometry in marine brown algae. The complexing agent was 1- (2- pyridylazo) – 2 - naphthol (PAN).The effects of various experimental parameters in the extraction ste...
متن کاملIon-pair formation of a copper(II)-ammine complex with an anionic surfactant and the recovery of copper(II) from ammonia medium by the surfactant-gel extraction method.
The extraction and separation of copper(II), zinc(II), cobalt(II), and cadmium(II) were investigated. Both copper(II) and zinc(II) formed ammine-complexes, while cadmium(II) and cobalt(II) formed hydroxide precipitates in an ammonia medium. By the addition of sodium dodecylsulfate (SDS), a copper(II) complex formed an ion-pair (copper-ammine-DS), which was extracted into the SDS phase. However,...

متن کاملSpectrophotometric determination of molybdenum using surfactant-mediated liquid–liquid extraction
A new spectrophotometric method has been developed for determination of molybdenum using surfactantmediated liquid–liquid extraction. Molybdenum(V) obtained by ascorbic acid reduction in 2.5 M H2SO4 reacted spontaneously with thiocyanate and cetyl trimethyl ammonium bromide (CTAB), forming an intense orange yellow complex that was extracted quantitatively into 1,2-dichloroethane and absorbed at...
