“…In the EME process, carrier concentration appears to be an effective factor for metal cation transport. 33 Type of carrier effect for Cr(VI) transport We achieved the transport experiments with two different carriers, di-(2-ethylhexyl) phosphate (DEHP) and Aliquat 336, to find out which carrier is more selective and effective against to Cr(VI). In the SLM-EME process, the choice of organic solvent is important for the correct operation of the system.…”

BACKGROUND: In this study, the transport of Cr (VI) ions was investigated with electroanalytical approach, called electromembrane extraction (EME), by using a supported liquid membrane (SLM).RESULTS: Aliquat 336 and Celgrad 2500 were used as a carrier and support material, respectively. Chromium (VI) ions were transferred from sample solution containing target analyte to extractant solution at low potential values (10-50 V) and with different current values (0.1-0.4 A). CONCLUSION:The following parameters such as carrier change, carrier concentration effects, solvent change effect were investigated and Cr(VI) transport was achieved with 54.73% recovery in 100 min at optimum conditions. In the EME-SLM process, Danesi mass transfer model was used to calculate the kinetic data, rate constant, flux, permeability, and recovery, for each parameter examined.

“…They come with several advantages, including high selectivity, easy preparation, and high extraction efficiency. [29][30][31] In the PIMs extraction, specic metal ions move through a reversible coordination-dissociation reaction between metal ions and extractants immobilized in the base polymer. 32 Studies have shown that PIMs exhibit good durability, long-term stability, and higher selectivity compared to SLMs.…”

“…The ELM technique may also be used to selectively separate heavy metal ions, according to previous research . For example, researchers have worked on the extraction and separation of nickel, copper, and other metals from ammonium carbonate/ammonium sulphate solutions using ELM . Calcium, nickel, and copper belong to the first transition series, which means that they follow the Irving‐William rule, which is that the relative stability of complexes formed by these transitions metals will be Ca < Ni < Cu .…”

The emulsion liquid membrane technique was utilized to selectively extract copper and nickel from a synthetic aqueous solution containing calcium, which was used to mimic a tailings stream found in the Sudbury region of Canada. The results showed copper and nickel ions were successively extracted from the synthetic solution. Two central composite designs and an analysis of the experiments were used to optimize the process and determine the main effects and interactions of experimental factors. In the first stage, copper was extracted with a minimum removal of nickel and calcium. It was found that under optimum conditions 98 % of the copper was extracted, with only 0.9 % of the nickel and 1.3 % of the calcium being extracted. The subsequent copper stripping efficiency was 95.7 %. In the second stage, the remaining aqueous solution was treated to remove nickel with minimum calcium removal. During this stage, the corresponding nickel and calcium removal percentages were 99.0 and 0.55 %, respectively, with a nickel stripping efficiency of 84.1 %. Laboratory bench‐scale tests using a two‐stage mixer‐settler showed a good correlation with these results when moving to a semi‐continuous process, which extracted 99.7 % of the copper and 98.2 % of the nickel, with only 2.2 % calcium extraction.
