The ELM technique has great potential for recovery and removal of different metal ions
and hydrocarbons from wastewater where conventional methods provide lower
In this study, Copper (II) ions was extracted from the aqueous solution using HPMBP as
the carrier, SPAN-80 as the surfactant, hydrochloric acid as the stripping agent, kerosene
as the solvent. Depending upon the solubility of carrier, surfactant, an optimum
composition of emulsion formation and extraction was designed. The important
parameters affecting the ELM extraction process including concentration of carrier,
concentration of surfactant and feed concentration were investigated. Based on the
optimum conditions like carrier concentration 6%V/V, surfactant concentration 5%V/V,
1NHCl (25ml), kerosene as a solvent, the ELM can extract 20.04 % copper ions from 50
ppm feed solution.
